FAQ

 

 

Q: What pressure is a pneumatic control valve?

A: Aluminium Pneumatic Flow Control Valve
Pressure Rating: Upto 10-12 kg/cm2.

Q: What are the applications of pneumatic valves?

A: The pneumatic valve can perform everything from switching a single flow path on and off to precise proportional control of pressure and flow. Most pneumatic valves have a control function, which can be defined as the operation of the valve in any process or the controlling of a quantity.

Q: What are the advantages of pneumatic control valves?

A: Increased safety is an advantage associated with pneumatic operated valves. Since they operate via air pressure, not electricity, there is a reduced risk of sparks or fires when using pneumatic operated valves in locations or applications that are flammable, hazardous or high-risk.

Q: What are the two main types of pneumatic control valves?

A: The following are the primary types of pneumatic valves:
3/2 way pneumatic directional control [single solenoid]
5/2 way pneumatic directional control valve [single solenoid]
5/3 way double solenoid directional control valve.
Pneumatic Spring Offset Valves.

Q: How does a pneumatic control valve work?

A: Pneumatic control valves use compressed air pressure to regulate the flow of fluids. They work by applying a pneumatic signal from a controller, which is then converted into air pressure to move the valve stem, opening or closing the valve and controlling the fluid flow. This movement is achieved through an actuator, often a diaphragm or piston, that responds to the applied air pressure.
