Product Description

702-21-57400 High quality hydraulic pump solenoid valve


Product introduction

702-21-57400 High quality hydraulic pump solenoid valve The solenoid valve uses the electromagnetic conversion principle of this mechanical energy to control the on-off of the oil circuit and realize the electrification control of the hydraulic oil circuit. The electromagnet in the solenoid valve of the hydraulic pump station usually consists of three main parts: the excitation coil, the static iron core and the moving iron core.

Product feature and application

702-21-57400 High quality hydraulic pump solenoid valve The working principle of the solenoid valve is to use the coil wound according to a certain rule to form a magnetic field after being energized (the power source is divided into DC and AC) to convert electrical energy into magnetic energy. After the electromagnet generates magnetic force, the iron core moves in a straight line to realize the conversion of electromagnetic energy into mechanical energy.
