Breather Valve Working Principle

Breather Valve, also known as direct acting Pressure/Vacuum Relief Valves, are special types of Relief Valves which are specifically designed

Pneumatic actuators are normally used to control processes requiring quick and accurate response, as they do not require a large

Solenoid valves may be used in such a way that they spend most of their time de-energized, energizing only for

When a pneumatic actuator requires air pressure applied to two different ports in order to move two different directions (such

3-way solenoid valves operate in a manner analogous to single-pole double-throw (SPDT) electrical switches: with two paths for flow sharing

2-way solenoid valves operate in a manner analogous to single-pole single-throw (SPST) electrical switches: with only one path for flow.

Valves, the actuators that move them, and the electronic circuits that control them, are all subject to aging soon after

A typical electric solenoid actuator is shown in Below Figure. It consists of a coil, armature, spring, and stem. Note
