Solenoid valves EVRA, servo operated, normally closed (NC)

Solenoid valves 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.

EVRAT is an assisted lift, servo operated solenoid valve for liquid, suction and hot gas lines with ammonia and fluorinated refrigerants.

EVRAT is specially designed to open - and stay open - at a pressure drop of 0 bar. The EVRAT solenoid valve is thus suitable for use in all plant where the required opening differential pressure is 0 bar.

EVRAT is available as components, i.e. valve body, flanges and coil must be ordered separately.

EVRAT 10, 15 and 20 all have spindle for manual operation.

EVRA 3-40, complete valves, incl. coil, excl. flanges

Refrigerants: R717 (NH3), R22, R134a, R404A, etc. Temperature of medium: -40 - +105°C. Max. 130°C during defrosting.

Servo Operated Solenoid Valve EVRA 32 & 40

Electromagnetic Valve

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 and the force of the compression spring.

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 kv value is the water flow in m3/h at a pressure drop across valve of 1 bar, ρ = 1000 kg/m3.
• MOPD for media in gas form is approx. 1 bar greater.
• For a. c. only
• For a. c. / d.c.
