Hydraulic solenoid coil

Valves operated by hydraulic solenoid coil are often used in agricultural irrigation systems. In this case, a relatively cheap small size solenoid is used to turn on or off a small front pilot valve, allowing a small amount of water to apply hydraulic pressure to the piston. The latter is mechanically coupled to the main valve and has sufficient force to switch the main valve.

The role of bistable solenoid valve in refrigerator refrigeration system

The main function of the solenoid valve in the refrigerator is to change the refrigerant flow direction, control the refrigeration state at different room temperature, optimize the refrigeration structure, achieve the goal ideal setting requirements, convenient for different users. There are many types of solenoid valve, currently popular refrigerator solenoid valve, mainly divided into two categories; One is a single - steady state solenoid valve, the other is a double - steady solenoid valve.  Bistable solenoid valve  is used to change the direction of refrigerant in refrigerator refrigeration system.
