Control valve
Thread Content
The control valve in the photo is driven by instrument air and has only two positions: fully open and fully closed. Can such a valve be called an electromagnetic valve, and what is the difference between it and an electromagnetic valve?
This is a pneumatic ball valve, equipped with a three-piece kit.
Is the photo of a pneumatic ball valve? There’s a solenoid valve behind the pressure reducing valve; the differences between these two valves are huge!
The solenoid valve is merely an accessory of the control valve
It seems to be a double-acting pneumatic actuator.
It is generally used at the inlet and outlet of containers, serving to open and close completely.

This is a pneumatic ball valve, which has many differences from solenoid valves.
This type of valve is generally denoted as XV- in flow diagrams; process engineers usually refer to it as a solenoid valve, and such solenoid valves are typically equipped with interlocks. The operation of the interlock is controlled by solenoid valves on the instrument air line to open or close completely. In short, the solenoid valves referred to by process engineers are not the same as those referred to by instrumentation professionals. The term \"solenoid valve\" used by instrumentation professionals refers to a solenoid valve as an individual unit.
