Solenoid Valve for Air Conditioner
General:
FDF series are direct or servo operated solenoid valves for liquid, suction, and hot gas lines with fluorinated refrigerants.
Characteristics:
Complete range of solenoid valves for refrigeration, freezing and air conditioning plant.
Supplied both normally closed (NC) and normally open (NO) with de-energized coils.
Wide choices of coils for A. C. And D. C
Suitable for all fluorinated refrigerants.
Opening pressure diff.:
Pilot type Direct-acting type
AC: 0.05-21bar AC: 0-21bar
DC: 0.05-17bar DC: 0-17bar
Max working pressure: 30bar.
Temperature of medium: -25º C~105º C.
FDF is also available with flange connections.
Versions with UL and CUL approval can be supplied to order.
Operating principle:
FDF-B, FDF-Z series solenoid valves are the direct-acting type valves. The pull of the solenoid coil opens the valve port directly by lifting the seat disc off the valve seat. While de-energized in the coil, plug stem will drop and close the valve port because of spring force and its weight.
FDF-M series solenoid valves are pilot type valves. While energized in coil, the coil emerges magnetic field and picks up plug stem to open the small orifice. With the pressure in the upside of valve reduced, the pressure difference between both side of diaphragm makes the 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 medium enters into upside of diaphragm through throttle hole, then pressure in both side of diaphragm, balances, then the diaphragm drops and closes the main orifice.
