Product Description

702-21-57400 Excavator Main Pump Solenoid Valve PC200-7   

Product introduction

702-21-57400 Excavator Main Pump Solenoid Valve PC200-7The 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 linearly to realize the conversion of electromagnetic energy into mechanical energy.
