Danfoss Solenoid valves EVRA20-25,EVR32-40 and EVRAT10-20 Danfoss valves introduction

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.
