Description


These stainless steel valves are used in fluid, intake, hot gas and oil return lines with ammonia or fluorinated refrigerants. The EVRS 3 and EVRST valves are designed such that they can be held open with a pressure loss of 0 bar, EVRS/EVRST 10, 15 and 20 can be manually operated. EVRS and ...


These stainless steel valves are used in fluid, intake, hot gas and oil return lines with ammonia or fluorinated refrigerants. The EVRS 3 and EVRST valves are designed such that they can be held open with a pressure loss of 0 bar, EVRS/EVRST 10, 15 and 20 can be manually operated. EVRS and EVRST are in the parts range, meaning that valve body and coil must be ordered separately.
