Pressure to Current (P/I) Converter Principle

We can construct a pressure to current converter using a Flapper- Nozzle arrangement , Bellows and a Linear Variable Differential

Current to Pressure Converter works on flapper nozzle method. The input is 4 to 20mA signal and the equivalent output

A very important signal conversion is from pressure to mechanical motion and vice versa. This conversion can be provided by a

Fail Open (Spring-to-Open, Air-to-Close) The actuator is spring-to-open, air-to-close type. Operation is via a normally closed 3 way, 2 position

The following factors are important in making the right commercial and technical choice for Solenoid Valve Selection Criteria: – Valve actuation

Control Valve Packing is a sealing system which normally consists of a deformable material, in the form of solid or

Are you preparing for the interview ? then you must study this article which covers basics of control valve interview

The Pneumatic Valve Positioner is an instrument working on force balance principle to position the Control Valve stem in accordance

Air Lock Relay is designed such that when the header / supply air pressure falls below the desired set value

In the pneumatic world, valves are the equivalent of relays controlling the flow of electricity in automation systems. Instead of
