What is a solenoid plunger?
A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work.
Which part of the solenoid is the plunger?
The solenoid plunger is the moving component of the solenoid and is generally in the form of a square or round rod or bar made from various ferrous alloys. When in the neutral or inactive position, the plunger is typically located with its one end near to or just inside the opening of the coil pocket.
How does a solenoid plunger work?
The valve features a solenoid, which is an electric coil with a movable ferromagnetic core (plunger) in its center. In the rest position, the plunger closes off a small orifice. An electric current through the coil creates a magnetic field. The magnetic field exerts an upwards force on the plunger opening the orifice.
How does a solenoid valve operate?
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.
What kind of valve is a solenoid plunger?
A solenoid valve is an on/off electromechanically operated valve which consists of an electromagnetic actuator (solenoid) and a valve body. The solenoid-plunger assembly is the valve actuator responsible for opening and closing the valve.
How does a solenoid valve open and close?
The solenoid-plunger assembly is the valve actuator responsible for opening and closing the valve. This actuator can be arranged in such a way that the plunger action can either open or close only. There is no intermediate, or in-between position, so there is no way for a solenoid to throttle flow.
How to install solenoid valve on Parker Hannifin?
1. Remove the coil assembly. 2. Locate the word IN or the directional arrow on the valve body. 3. Place the valve in the line, in the proper direction of flow and solder. 4. installation instructions.Replace the coil assembly and tighten coil hex screw.
What kind of material is a solenoid valve made of?
It’s usually cylindrical in shape and made of ferromagnetic material. When the solenoid coil energizes and produces a magnetic field, the plunger moves up or down. Depending on the action required and the working mechanism of the valve, the plunger movement controls the media in the valve.
