Solenlid valves are electrically-controlled openor closed refrigerant flow control valves desgned for use in liquid,suction and hot gas lines.A normally closed solenoid vavle is closed when the coil is de-energised and the plunger is seated.When the solenoid coil is enlarged,the magnetic effect of the coil lifts the plunger and opens the vavle.

Normally open solenoid valves have reverse action.

They are used in refrigeration systems for refrigerators and freezer display cabinets,cold stores and deep freeze stores,milk coolers,water coolers and in air-conditioning plants.
