    042H1142 EVRA 40 Ammonia Refrigerants Servo Operated Piston Refrigeration Solenoid Valve With Butt Weld Connections

     

    EVRA40 solenoid valve is designed mainly for ammonia refrigerants, it is supplied complete or as separate components, i.e. valve body, coil and
    flanges can be ordered separately.

     

    Technical data:

    Refrigerants:Applicable to HCFC, HFC and R717 (Ammonia).

    1) The kv value is the water flow in m3/h at a pressure drop across valve of 1 bar, ρ = 1000 kg/m3.

    2) MOPD for media in gas form is approx. 1 bar greater.

    EVRA 25, 32 and 40 are servo operated piston valves. The valves are closed with currentless coil. The servo piston (80) with main valve plate (84) closes against the valve seat (83) by means of the differential pressure between inlet and outlet side of the valve, the force of the compression spring (76) and possibly the piston weight. When current to the coil is switched on, the pilot orifice (29) 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.
