Is Solenoid Valve an Actuator?

Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.

Is a solenoid an actuator?

In electromagnetic technology, a solenoid is an actuator assembly with a sliding ferromagnetic plunger inside the coil. Without power, the plunger extends for part of its length outside the coil; applying power pulls the plunger into the coil.

How is a solenoid valve different from an actuator?

Solenoid valves use electromagnets to move a plunger attached to the valve to open or close it. Motorized Valve is driven by a electric actuator, it takes longer than the solenoid valve to open or close. The actuator can be controlled by current signal (4~20mA) or voltage signal (0~ 10V) to regulate the flow.
