Based on advanced technology the ICF EVRAT retrofit valve incorporates three functions in one housing, which can replace the widely used direct coupled FA + EVRAT, as a drop-in solution. The two function modules - solenoid valve and manual opener are identical to the function modules in the ICF 20 valve station concept thus facilitating logistic and service. The solenoid valve is an assisted, servo operated valve for liquid, suction and hot gas lines with ammonia and flourinated refrigerants. Supplied as a complete assembly, it is fully tested at high pressure and its functions are tested under factory controlled conditions.
