What Are Hydraulic Solenoid Valves And How To Test | Finotek
The armature sleeve assembly converts the magnetic force into a pulling force or thrust force in a magnetic field. The hydraulic solenoid valve parts assembly utilizes this force to overcome the spring force and the liquid force, to opens or closes the corresponding flow channel. The solenoid coils are fixed with nuts for easy replacement.
280239 10333044 24V Liebherr Excavator Pilot Solenoid Valve Coil
Description. Solenoid valve coil is designed to convert electrical energy into lateral motion. The coil usually consists of copper wire wound around a hollow bobine or tube so when electric current flows through the coil, a magnetic field is generated. By placing a solenoid valve coil over a ferromagnetic core (usually magnetic 430F stainless ...
