Here’s How To Choose The Right Types Of Valves In Piping For You

types of valves in piping

In this case, we will be discussing the different types of valves that can be found in piping.

Piping is an important part of any building. It is used to transport water, gas, steam, and sometimes even air. Sometimes, you will find a pipe and then you will ask, “What kind of valve is this?” This is where you need to know the answer to that question.

There are several different types of valves that can be used in piping. The three most common ones are check valves, ball valves, and gate valves.

A check valve is a very common type of valve.

Pinch Valve

Pinch Valve

A pinch valve is a very common kind of valve that you will find on almost any home water system. It has a brass body with a plastic or rubber handle that fits into a metal seat. There are several different kinds of pinch valves. The one shown here is the standard “one-way” type. 

This kind of valve only allows water to flow in one direction. If you turn the handle clockwise, it will shut off the flow of water. However, if you turn the handle counterclockwise, it will open up the flow of water again.

This kind of valve is very common and it is used for two reasons. The first reason is because it is easy to operate. The second reason is because it is very effective at stopping leaks. It is also easy to replace should it become damaged.

Gate Valves

Gate Valves

A gate valve is a very common type of valve used on water heaters. It is a circular disc that sits atop a vertical post. A weighted arm is attached to the top of the post. The top of the valve has a circular opening with a spring-loaded gate or disc inside it.

To open the valve, you have to lift the weighted arm, which causes the valve to rise up off of the post. This allows the flow of water through the pipe. To close the valve, all you have to do is drop the weighted arm and the valve will fall back down onto the post. This action will stop the flow of water through the pipe.

There are many different types of gate valves. They are made by different manufacturers and they have slightly different features. The most common type of gate valve used on water heaters is the plain old garden-variety gate valve. It is the least expensive type of valve and it is very common.

Globe Valves

Globe Valves

A globe valve is a three-way ball valve with an outer ring that rotates freely inside the body of the valve. This allows you to control the flow of water in both directions. It has a wide variety of uses, from controlling the flow of water in a sprinkler system to controlling the flow of water in a garden hose. Globe valves are easy to install and maintain. They come in different sizes and are made of durable materials.

Needle Valves

A needle-pipe type valve is a standard type of valve used for controlling the flow of water in a sprinkler system. It is also known as a “dumb” or “non-smart” valve because it does not have an internal computer that regulates the flow of water. This type of valve is inexpensive and easy to install, but it has some disadvantages too.

One of the main disadvantages is that it will only open a certain amount of water per minute. Another disadvantage is that it can only be adjusted so far up or down. In some cases, this type of valve can be adjusted so far that it will actually shut off water completely. However, if the adjustment is not made far enough, you may find that your lawn is not getting enough water.

Butterfly Valves

Butterfly valves are very common in industrial applications, but they are also used in home appliances and HVAC systems. They are designed to open and close with extreme speed and are made of durable materials such as stainless steel.

Butterfly valves are very useful for controlling the flow of gas or liquid. For example, they can be used to control the flow of refrigerant in an air conditioning system. The butterfly valve is attached to the refrigerant line and it has a small stem that fits into a round opening. 

When the valve is open, the stem extends out of the opening and the butterfly valve allows the refrigerant to flow freely through the tube.  However, when the valve is closed, the stem is completely sealed in the round opening and the flow of refrigerant is stopped.

Ball Valves

Ball Valves

A ball valve is a type of three-way valve that has a round, hemispherical body with one or more circular openings.  The opening at the top of the ball valve is usually threaded so that a union can be screwed onto it.

The bottom of the ball valve is flat and can be attached to a pipe or hose using a nut and washer arrangement or any other type of fastening device.  When the union is screwed onto the top of the ball valve, it creates a seal around the entire circumference of the ball.  This prevents fluid from flowing through the valve when the screw is not turned.

However, when the union is unscrewed from the ball, the opening in the ball allows the fluid to flow through the valve.  In this way, a ball valve can be used as a on/off valve or as a proportional valve.

Plug Valves

A plug valve is a mechanical device that has two parts. One part is a sphere that fits into another part which has a threaded hole in it. When you screw the sphere into the hole, it seals the threaded area. Then, you can turn a knob or move a lever to open or close the flow of water through this device.

You can use a plug valve to control the flow of water from a faucet or from a hose bib. You can also use one to control the flow of water in a garden hose. In a toilet, you can use one to control the flow of water to the bowl. A plug valve will regulate the amount of water that flows to the bowl. It will not, however, affect the pressure. The pressure of the water that flows to the bowl is controlled by your main water supply.

Aerosol Valves

Aerosol Valves

An aerosol valve is a small plastic or metal device that is installed onto the end of an aerosol container. It controls the flow of the propellant gas from the container. Most aerosol valves have an integral spout or orifice that allows the contents of the container to be dispensed. However, some containers have a threaded orifice instead of a spout. In this case, a cap is screwed onto the orifice to control the flow of the contents.

Air Logic Valves

An air logic valve is a device used to control the flow of air into an air conditioner or heater system. It is a mechanical or electromechanical device that is attached to the outside of the air handler or furnace.

It works on the same principal as a ball valve. The only difference is that it has a much larger orifice. This allows you to regulate the flow of air into the unit with greater accuracy. You can use an air logic valve to reduce the capacity of the unit so that it will run more efficiently. You can also use it to increase the capacity of the unit so that it will cool or heat your house more quickly.

Balancing Valves

Balancing Valves

A balancing valve is a device that is used to equalize the pressure of two different liquids. If one of the liquids is a gas, the balancing valve will equalize the pressure of that liquid so that both liquids are at the same pressure. This allows you to mix the liquids together without any problems.

If the liquids are not gases, then the balancing valve will allow the liquids to maintain their respective pressures. This prevents the liquids from mixing together. A common example of this is a faucet. If the water coming out of the faucet is too hard, you can use a knob or lever to adjust the setting so that the water comes out at a more gentle flow. However, if the water is too soft, there is no adjustment needed. It will come out at the proper pressure to keep the water from spilling out of the spout.

Blind Valves

A blind valve is a valve that has a round, flat disk or “button” attached to its stem. This button covers the entire top of the valve and stops water from flowing when the valve is turned off. When the valve is turned back on, the button lifts up and lets the water flow freely. This type of valve is used when you want a very tight shut off, but also when you need to have some flexibility in controlling the water flow.

Blind valves are used in many different types of plumbing fixtures, including faucets, shower heads, toilets, urinals, etc. They are also used in irrigation systems and in some types of pool equipment.

Cartridge Valves

It consists of a cylindrical cartridge with holes in it, a valve body with a spring-loaded plunger, and a handle or lever to operate the device. Cartridge valves are used in many different applications, including fountains, irrigation systems, hydronic heating, and household use. Cartridge valves are much less expensive than other types of valves and they are very easy to install.

Cartridge valves work on the principal of a ball and a socket. The end of the valve body has a socket that fits over the top of the cartridge. Inside the cartridge are tiny spherical balls that fit into the socket. As the handle is turned, the spherical ball moves up and down inside the cartridge. This action opens and closes the water flow.

Casing Valves

Casing valves are valves that are used to control the flow of fluid in a pipeline. They are located at the ends of the pipe sections that make up the pipeline. The valves are designed so that they can be opened or closed from the inside of the pipe.

This is important because it allows the owner of the pipeline to shut off the flow of fluid in the event that there is a leak in the pipe. It also prevents fluid from flowing when it is not needed.

Check Valves

Check Valves

A check valve is a mechanical device that allows fluid to flow in one direction only. This keeps the fluid from flowing back in the direction it came from. A simple example is a toilet. If you flush the toilet and there is no water in the tank below the toilet, the water in the tank will not flow down into the toilet. However, if the water in the tank becomes full or overfull, the water will begin to flow down into the toilet until the tank is empty or underfilled.

Check valves are used in many different types of applications. They are used in control valves on steam engines, gas pumps, and even in car tires. They are so important, they are required on almost all boats and are often referred to as “the lifeline of the boat owner.


How Do Valves Work?

Valves are used to control the flow of liquids or gasses through a pipe or hose. They are usually made out of metal and have a gate or plug that allows the flow to pass through. When the valve is closed, the flow can not pass through.

There are several types of valves including ball, butterfly, diaphragm, gate and more. In the case of a gate valve, there are two halves that are held together by a pin or bolt.

How are valves made?

Valves are made in a variety of ways, but they are most commonly made from forged brass, ductile iron, steel castings, and cast stainless steel.

The type of material used to make the valve body determines what sort of sealing action it will have. Forged valves are best for high pressure service where the stem can be hardening hardened.

What are the parts of a valve?

Valves have two parts: the valve body and the valve stem. The valve body is the part that is attached to the piping system and the valve stem is the part that is attached to the device that operates the valve.

The valve stem has a threaded end that screws into the device that operates the valve and a non-threaded end that has a small (1/2 inch or less) diameter section called the “valve bonnet”.


Piping has valves inside of it. These valves control the flow of water or gas. The most common ones are called ball valves and they have a round knob on them and a hole that has a round ball inside of it.

There are many different types of valves in piping. You should be very careful when you are working with them because if you don’t know what you are doing, you can cause serious problems. So, it is very important to learn how to identify all of the different types of valves that are in your home or business.
