Solenoid Valve Actuator
Solenoid valve actuator
The electric actuator is equipped with manual operation device, which can operate the control valve to on/off manually without installing bypass for backup. But the general solenoid valve has no manual operation function, the pipeline needs to install bypass manual valve for backup.
How does a solenoid actuated valve work?
Solenoid valves consist of a coil, plunger and sleeve assembly. In normally closed valves, a plunger return spring holds the plunger against the orifice and prevents flow. Once the solenoid coil is energized, the resultant magnetic field raises the plunger, enabling flow.
Is a solenoid considered 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. Electromagnets with fixed cores are not considered solenoids.
