Pneumatic Flow Control Valve Types

Different types of flow control valves are available because each has a slightly different function.

Pneumatic flow control valve types.

Their selection and placement within a pneumatic circuit will greatly affect the function of an actuator. For example in a two way directional valve the valve is either open air flow is enabled or closed air flow is prevented. Ii air to close. This enables the direct control of flow rate and the consequential control of process quantities such as pressure temperature and liquid level.

Pneumatic flow control and needle valves help you regulate air flow in your compressed air system. A types of control valves based on action. Some valves are complex enough to adjust automatically to pressure and temperature variations no matter their construction flow control valves are designed to regulate the flow or pressure of fluids and they. In automatic control terminology a control valve is termed a final control element.

Pneumatic threshold sensors detect the end of an air cylinder stroke and signal when pressure drops. The variations between devices allow for pneumatic systems to work properly. We offer two types of air flow control valves. Choose the inlet and outlet port types in sizes that can fit your application.

Also known as 4 way and 5 3 closed center valves. Spring offset pneumatic valves. Solenoid air control valves rely on electromagnetic levers for controlling air flow and release to achieve proper compressor function. A meter in flow control valve also known as a reverse flow control valve restricts the flow to an actuator.

The primary function of a flow control valve is to regulate the pressure of a flow of fluid in a pneumatic system. The hydraulic actuators respond to changes of pressure or flow and will open close the valve. There are countless types of valves for use across a variety of industries and applications. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.

Automatic control valves do not require an external power source meaning that the fluid pressure is enough to open and close them. This type of pneumatic valve classification refers to the manner in which air flow direction is switched. A needle valve features a small port and threaded needle shaped plunger and can allow precise flow regulation at lower flow rates. They are designed such that if the air supply fails the control valve will be either fully open or fully closed depending upon the safety requirement of the process.

A meter out flow control valve regulates the exhaust flow from an actuator. They create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. When it comes to flow control valves valve types range from simple to sophisticated. Pneumatic flow control and needle valves regulate the flow of compressed air.
