Gate Valves Vs. Ball Valves: What Are The Differences?

When it comes to piping valves, there are many options available with different size and shape for you to choose. But in term of popularity, Gate valve and Ball valve are among the most commonly used valve type due to their excellent performance. Nonetheless, these valves have unique characteristics so you should not use them without proper consideration and planning beforehand.

Gate valves vs. Ball valves, it’s not easy to tell which one is the better choice, especially if you know little about them. In the case you wish to learn more about the valves and the way they work, you come to right place. Here is a comprehensive analysis of these valves along with their advantages and disadvantages in different applications.

Gate valves

What is a gate valve?

The gate valve earns its name from its internal mechanism which includes a round or rectangular wedge that serves as a stream gate. By moving the wedge up and down through an external handle, you would be able to control the liquid stream.

In the usual case, the gate valve is used to start/stop the liquid flow, it’s rarely used for stream regulating. A gate valve tends to have two ports, an outlet and an inlet. Many gate valves utilize threaded ports but flanged and soldered designs are also available.

The valve application

Due to its ability to slice through the liquid with ease, the gate valve is widely employed in the petroleum business. Household arrangements also utilize gate valves as well and the valve popularity in the area is increasing steadily. Typical gate valves are designed to be closed or opened completely so as to reduce potential friction loss.

The valve style

  • PVC Gate Valves: These valves are flexible, tough and generally affordable to the average person. This valve style is primarily used where temperature and pressure are not big issues such as cold water household systems.
  • Brass Gate Valves: If corrosion is a serious problem, this is the valve you should use. It’s also able to endure high temperature so the valve is often used in manufacturing applications.
  • Stainless Steel Gate Valves: Thanks to its rust free and corrosion resistant material, the valve is a good choice when corrosion reaches an epidemic level. Since stainless steel would not leach into the water, you don’t have to worry too much about metal contamination and alike. As a result, it’s could withstand weather element, human error as well as tree roots.

Advantages and disadvantages.

One notable strong point of the gate valve is that it would not cause a water hammer due to the valve slow mechanism. If you don’t know, water hammer is a pressure surge caused when the liquid stream is suddenly forced to stop. Water hammer could lead to major problems such as excessive vibration and noise or even a total pipe collapse.

However, gate valves also have a couple of drawbacks relate to its screw handle mechanism. When the valve mechanism is corroded, the valve would no longer work properly. On several valve models, the wedge could get stuck in the partially closed or partially open position which could accelerate the wearing rate.

Compare with other valves

Butterfly valve vs. Gate valve

Butterfly valves are lighter and more compact than gate valves which make them are a good choice for cramped applications. However, butterfly valves are unable to handle corrosion, inflammable and hazardous materials. They mostly used for low temperature and low-pressure arrangement.

Plug valve vs. Gate valve

Plug valves are ideal choices when it comes to quick shutoff and generally economical to operate. Nonetheless, because of the high friction, it’s only employed for precise throttling/modulating.

Globe valve vs. Gate valve

In contrast with gate valves, globe valves are usually designed to regulate the flow rate of the stream. Due to its construction, the glove valve is less vulnerable to seat leakage compared to other valves. You cannot set the valve in any directional flow through.

Stop valve vs. Gate valve

For most of the time, stop valves are often used for household fixtures such as toilets and sinks. They utilize a rubber gasket to shut off the water flow which is not as reliable and efficient as the gate valve wedge.

Ball valves

What is a ball valve?

As the name suggests, ball valves utilize a compact sphere to shutoff the flow of liquid. The sphere itself has a hole, aligning the hole with the pipe would allow the stream to move freely through it. On the other hand, when the hole is perpendicular to the pipe, the flow is stopped entirely.

You could control the ball position through a lever on top. Usually, moving the lever at 90-degree angle would permit stream to pass through or cut it off. The lever is designed in a way that you cannot rotate it more than 90 degrees. In the usual case, the ball is placed on a valve seat with the stern inserted on top of it.

The valve application

Thanks to its robustness and simplicity, the ball valve is used in many applications such as petroleum, household, marine, pharmaceuticals as well as heavy industry. Since it could be designed so the lever rotation is approximately proportional to the flow rate, the valve is able to prove active stream regulation. That is why it’s widely used in a variety of application.

The valve style

  • PVC Ball Valves: These valves are excellent combinations of flexibility and affordability. They are mostly used when heat and pressure are not serious concerns.
  • Brass Ball Valves: This valve type handles heat pretty well so it’s commonly used for high-temperature applications.
  • Bronze Ball Valves: Mainly found on ships because the valve is able to endure constant exposure to seawater.
  • Stainless Steel Ball Valves: Well appreciated for their strength and overall resistances, these valves are what you need when it comes to chemical and water applications.

Advantages and disadvantages.

Ball valves are simple to activate and deactivate so they could be operated by someone who could not manipulate a wheel type valve.  Moreover, you are able to tell the valve position at a glance. In most of the case, ball valves possess high endurance, excellent versatility and long lifespan. They would work reliably for years to come without running into any troubles.

However, the ball valve does have some shortcomings such its requirement for space. Several applications may not have enough room for you to rotate the handle which somewhat limits the use of ball valve. The ball valve could occasionally cause a water hammer situation as well.

Compare with other valves

Globe valve vs. Ball valve

For shutoff applications, people prefer to use ball valves but globe valves are superior at regulating the flow rate. If you want to have excellent throttling control, you should consider using globe valves.

Plug valve vs. Ball valve

In general, the ball valve could offer you a certain degree of throttling control which is much better than the plug valves. In addition, ball valves could function well for years while plug valves may get stuck eventually and therefore become difficult to operate. Beyond that, these valves are quite similar and even interchangeable in some cases.

Butterfly valve vs. Ball valve

When it comes to endurance, ball valves are capable of handling moderate pressure and temperature floatation. In contrast, butterfly valves could only be used in low pressure and low-temperature applications.

Conclusion

And that is most of what you should know about these valves, not too hard to absorb, right? Gate valves vs. Ball valves, it’s not easy to decide the winner without taking into account your needs and requirements. But with the help of this article, you should be able to decide the right valve type to use for your piping system.

How to Avoid Danger in Disposing Gasoline

Why would you store gasoline when you do not see any immediate need for it? Or a better question would be, “Why would you buy gasoline more than you need?”

The danger of storing gasoline in a household cannot be stressed enough. While we have become overly dependent on gasoline in many aspects in our daily routine, we cannot disregard safety measures when it comes to handling such hazardous chemical.

The succeeding discussion will enlighten you on preventive measures when storing gasoline as well as show you how to dispose of gasoline to avoid any untoward incidents. However, before we get into the “how to,” let me share with you some facts on the dangers I am talking about.

FACTS

  • A project sponsored by the American Society for Testing and Materials conducted by the Worcester Polytechnic Institute on the flammability hazard of gas cans found out conditions that can result in “flashback” explosion. The study further revealed that when gas vapor escapes from the can and a spark or flame is present, this can cause ignition and flashback which then results in an explosion. The study likewise stressed that it doesn’t take a full gas can for an explosion to occur.
  • Gasoline has ignitable, reactive and combustible properties hence considered as hazardous material. Storage of such is highly regulated. But despite the regulation, the danger of storing even a little amount of gasoline is beyond debate. CNBC, in its published news, reported eleven (11) deaths in addition to 1,200 emergency room cases associated with explosions of gasoline cans since 1998.

PREVENTIVE MEASURES

Because the danger is ever present as well as the need for gasoline, we should be knowledgeable on how we can prevent accidents whenever storing and handling gasoline.

#1: Check for local and state regulations

Taking time to be educated on government standards on gasoline storage will do you good. As a homeowner, it is your responsibility to know restrictions on gasoline storage. You do not only have the responsibility to protect yourself, your family and home but your community as well.

Most often restriction only allows up to 25 gallons. Gasoline must be in prescribed containers of which capacity of each container does not exceed five (5) gallons. The Occupational Safety and Health Administration (OSHA) have specifications on container requirement. OSHA 1926.152(a)(1) states the following:

  • All flammable liquids should be contained in no more than 5 gallons capacity can. Should there be a need to store more than 25 gallons, you should have a storage room for that purpose. Therefore it is safe to say that gasoline cans less than 5 gallons capacity satisfy the governmental requirement.

SureCan – Gas Can with Rotating Spout, OSHA approved

  • A flash arresting screen is a pre-requisite for a gasoline container to be approved by OSHA. It has an extremely important function in preventing combustion from taking place inside the can whenever there is fire. In simpler explanation, the screen stops fire even before it reaches the gas.
  • Gasoline cans should not be difficult to seal. OSHA requires containers to be equipped with a spring-closing lid. The lid closes by itself upon release and thus it avoids users from forgetting to close it. At the same time, the lid should be secured enough so as not to release so much vapor. Moreover, the can should have a child-resistant cap.
  • Apart from that, approval seals are important. When buying gasoline in cans, be sure to look for the Department of Transportation approval or any recognized testing laboratory.

#2: Ensure proper storage

  • Keep gasoline away from your house. Place it in your shed for instance. OSHA 1926.152(a) (1) specifies requirements for storing flammable liquids. It must be kept in areas where there is not much traffic. Never place it in stairways or areas where people come and go.
  • Makes sure there is good ventilation in your storage area. There is definitely danger when gasoline is exposed to hot temperature. Keep it somewhere where room temperature is preserved, OSHA 1917.156(b) (2) (iv).

#3: Handle with extra care

<img class=”tve_image” alt=”” style=”width: 200px;” src=”//homienjoy.com/wp-content/uploads/2017/02/bigstock__124448072__1488187054_86891.jpg” scale=”0″ width=”200″ height=”284″>

Danger highly flammable liquid yellow warning sign

  • A warning sign is helpful, “Flammable-Keep Away from Open Flames.”Containers must be tightly closed.
  • Extra care must be observed during handling to avoid spills.
  • Ensure distance from anything that can cause ignition. Safe distance would be 50 feet.
  • Should you need to put gasoline into machines such as a lawnmower, allow it to cool before doing so.
  • Never allow children to have access to gasoline.
  • In the case of minor spillage, sawdust comes in handy in absorbing the spill. Paper and rags are also options.
  • For larger spills, it is advisable to check with your local government unit to ensure safety.

HOW TO DISPOSE OF GASOLINE

Now that you have an idea on how to handle gasoline especially in your property, it is also equally important to discuss how to dispose of gasoline in case you have bad or excess gas at home. DO NOT dispose of gasoline just about anywhere. Should the idea of throwing gas on a street drain, ground, sewer and the like or maybe putting it together with your garbage, THINK AGAIN!

First of all, it will harm the environment. The danger of explosion and contamination is extremely probable. Secondly, doing such can get you into trouble with government authorities. You can be penalized for improper disposal of hazardous material apart from being criminally liable. It is a Federal offense!

Below are some of the ways to safely dispose of gasoline.

#1: Recycle old gas

You can bring it to a car shop or even boat yards. These people know how to put old gas to use. Others would mix it up with new gasoline and use it for lawnmowers. Just a reminder, do not use it for your car.

If you want to do it yourself, I will show you how.

+ Be sure to have the following:

  • a plastic funnel
  • extra container preferably glass bottle
  • Paper towels for filtering.

+ Set aside old gas.

+ Make your filter by placing a sheet of paper towel folded to fit into the funnel.

+ Once your filter is ready, get your glass bottle and put the funnel into the bottle’s opening.

+ Gradually pour the old gasoline through the funnel.

+ Change paper towel when necessary.

Now that you have filtered the old gas, you are now ready to mix the filtered gas with fresh gas.

The ratio is four (4) parts new gasoline and one (1) part gasoline. The result is called reconditioned gasoline.

If you are not confident in doing it by yourself, here are some other options:

#2: Ask professional advice from Fire Department

Pay your Fire Department a visit or maybe you can give them a call. They should be able to give you recommendations for best action to take.

#3: Check for HHW Facility

Check for Household Hazardous Waste Facility in your area which offers free services. Usually, they have landfills where you can bring hazardous waste and you can just drop them there. Of course, you will need to comply with packaging and labeling requirements.

There are also service providers you can find in the yellow pages. All you need to do is look for these businesses under Environmental and Ecological Services and Oils, Waste.

Danger relating to handling, storing and disposing of gasoline can be avoided. Take all precautionary measures to avoid loss of life and property. When it’s gone, you cannot just say, “I told you so.” You must realize the hazard of chemicals such as gasoline presents.

It is also good to emphasize that proper disposal of gasoline means recycling the gasoline. In this day and age when depletion of natural resources is also a pressing problem, properly disposing of your old gas lets you contribute to the betterment of our planet.

The discussion provided above should be an excellent reference. You might want to go over the discussion one more time. Should you have questions, feel free to comment and I’ll be glad to respond.
