EVRS 3-20/EVRST 10-20 Stainless Steel Solenoid Valve
Brand: Danfoss
EVRS and EVRST are valves made of stainless steel.
- EVRS 3 is direct operated.
- EVRS 10, 15 and 20 are servo operated.
- EVRST 10,15 and 20 are forced servo operated.
The valves are used in liquid, suction, hot gas and oil return lines with ammonia or fluorinated refrigerants.
EVRS 3 and EVRST are designed for keeping open at a pressure drop of 0 bar. EVRS/EVRST 10, 15 and 20 are equipped with spindel for manual opening.
EVRS and EVRST are supplied as components, i.e. valve body and coil must be separately ordered.
