Application:
1. Used into liquid line, suction line and steam line of refrigeration system to control the refrigerant to pass or not
2.Used in refrigeration compressor group, central air-conditioning, cold storage equipment
and bus air-conditioning system.
 

Operating principle:
While energized in coil, the electromagnetic power opens the small orifice. Then the pressure in upside of valve reduced, so the pressure difference between both side of diaphragm happen and lead to diaphragm lift to open the main orifice. While de-energized in the coil, plug stem will drop and close the small orifice because of spring force and its weight. The flow media enters into upside of diaphragm through throttle hole, then pressure in both side of diaphragm balances, then the diaphragm will drop and close the main orifice.
