19 types of valves used in piping. / Different types of valves. / Classification of plumbing valves.

 The different types of valves with their images are given to gain basic knowledge of them and their mechanism.

1. Ball valve:

These valves contain hollow balls to control the flow of liquid. Ball valves are quarter-turn valves with their handles turning at 90 degrees in either direction to regulate the flow.

2. Gate valve:

 They contain gate-like barriers for the flow of water, that can be lifted up & down by turning the wheel-type handles. Gate valves are usually used for the complete flow of water without obstruction, rather than regulating the flow.

3. Bibcock valve:

This is the most common type of valve, usually referred to as a tap (valve). These valves are used in bathrooms, sinks, basins, etc. to control water flow. 

4.  Flapper valve:

You can observe these types of valves in the flush tank of the toilets, which controls the water flow. They contain flaps and rubber seals to open and close, according to the level of water in the flush tank. 

5. Plunger valve:

These types of valves are used when the pressure of the flow should be controlled precisely and safely. Plunger valves provide a symmetrical flow pattern due to the built-in cylinders and rings. 

6. Spool valve:

These types of valves are used in controlling the flow of hydraulic fluids. They are further classified as rotary or sliding-type spool valves. 

7.  Needle valve:

Needle valves are used for the precise control of the flow pressure when the flow rate is in a lower quantity. They contain a needle-shaped plunger to regulate the flow.

8. Pilot valve:

These types of valves are used for the limited supply of flow feed under higher pressure.

9.  Clapper valve:

These valves allow the flow of feed in one direction. They have a mechanical device attached to the hinge for the opening and closing movement.

10. Globe valve:

They contain a disc-shaped plug at the end of the shaft to control the flow. They operate on the linear motion system for the regulation of feed.

11.  Pressure valve:

They are the safety valves used to control the maximum allowable pressure or to limit the pressure as per the safety norms. So the pressure valves are also said as relief valves.

12. Choke valve:

They contain a solid cylinder within a hollow cylinder to control the flow. The inner cylinder blocks or opens to provide a steady flow of the feed.

13.  Diaphragm valve:

In these types of valves, a flexible membrane known as a diaphragm is used for fluid control. They are throttle valves having bi-directional flow. 

14.  Pinch valve:

They contain rubber sleeves, that pinche when operated to obstruct the flow of materials. These types of valves are used in industrial productions like pharmaceuticals, food, beverage, cement factories, etc. to control the flow of granules.

15.  Plug valve:

Plug valves contain tapered cylindrical or conical inner plug-like bodies to regulate the flow. They are quarter-turn valves having a 90-degree rotation of the handles.

16.  Check valve:

They are non-return or one-way valves, that generally allows the fluid to pass in one direction. The check valves have two openings in the body, where one enables entry and the other provides exit of the entered fluid.

17.  Butterfly valve:

These valves have a round disc body that turns in 90 degrees when operated to control the flow. Butterfly valves are used in handling the flow of slurries that contain suspended matter, as they provide a free flow of fluids without much obstruction.

18.  Disc valve:

They are closure devices used in controlling fluids as well as airflow. In the diffuser system, you can find such valves for air control.  A disc-shaped body de-pressurizes the feed and helps in regulating the flow.

19.  Foot valve:

 The foot valve is a type of check valve, that allows unidirectional flow. They are installed at the end of the suction pipe for lifting water from the wells and tanks, using water pumps.
