Product Details

Ammonia NH3 Solenoid Valve For Refrigeration

EVRA is a direct or servo operated solenoid valve for liquid, suction and hot gas lines with ammonia or ﬂuorinated refrigerants.
EVRA valves are supplied complete or as separate components, i.e. valve body, coil and ﬂanges can be ordered separately.
EVRA 25, 32 and 40 are servo operated piston valves.The valves are closed with currentless coil.The servo piston with main valve plate closes against the valve seat by means of the differential pressure between inlet and outlet side of the valve, the force of the compression spring and possibly the piston weight. When current to the coil is switched on, the pilot orifice opens. This relieves the pressure on the piston spring side of the valve. The differential pressure will then open the valve. The minimum differential pressure needed for full opening of the valves is 0.2 bar.
