Pneumatic manual control valves form part of a pneumatic control system and allow the user to control the flow of air from one place to another.

Pneumatic control valve components.

Control valve is a final control element final control elements are necessary to control the process variable. We ve been supplying pneumatic components for more than 40 years. Flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit resulting in a slower actuator speed. Actuator is a mechanism which moves or control a device such as a valve.

Regardless of type all valves have the following basic parts. This version of internet explorer is either no longer supported by microsoft or is obsolete and some features of our store may no longer be supported. Valves are used to control the flow of fluid in process system.

They are often constructed as modular devices meaning multiple valves and contacts can be used in conjunction with one another to create many different system combinations. 3 basic types of actuators are there pneumatic. The body bonnet trim internal elements actuator and packing. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.

2 body part for easy understanding. Control valves mainly have two parts. Main parts of control valve are valve body and actuator actuators are used to position the valves. Designed and manufactured in the usa our pneumatic valves fittings manifolds and custom pneumatic components are relied upon for fluid control throughout a wide variety of industries.

In automatic control terminology a control valve is termed a final control element. Symbols for valves are shown as boxes representing the different operating positions the symbol shown for example is based on two boxes so it is a two position or 2 stage valve. Selecting the right flow control valve.

Basic parts of control valves. This enables the direct control of flow rate and the consequential control of process quantities such as pressure temperature and liquid level. The basic parts of a valve are illustrated in figure 1. Pneumatically controlled devices use pneumatic valves to control and direct the air and enable operations such as lifting moving pressing etc.
