2. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   The servo valves of the World War II-era were similar to this — using a solenoid to drive a spool valve. Advancement of EHSVs took off in the 1950s, largely due to the adoption of permanent magnet torque motors as the first stage (as opposed to solenoids).

3. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   A solenoid valve is an electromechanically operated valve. Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid, and the type and characteristics of fluid they control. The mechanism varies from linear action, plunger-type ...

4. Partial stroke testing - Wikipedia

   en.wikipedia.org/wiki/Partial_stroke_testing

   Partial stroke testing. Partial stroke testing (or PST) is a technique used in a control system to allow the user to test a percentage of the possible failure modes of a shut down valve without the need to physically close the valve. PST is used to assist in determining that the safety function will operate on demand.

5. Solenoid (engineering) - Wikipedia

   en.wikipedia.org/wiki/Solenoid_(engineering)

   In engineering, a solenoid is a device that converts electrical energy to mechanical energy, using an electromagnet formed from a coil of wire. The device creates a magnetic field [1] from electric current, and uses the magnetic field to create linear motion. [2][3][4] In electromagnetic technology, a solenoid is an actuator assembly with a ...
