The Vilter Outer Seat, Ammonia or R12 & R22 Discharge Valve with Helical Springs is a precision-engineered component designed for use in Vilter compressors operating with ammonia (R717), R12, or R22 refrigerants. The outer seat provides a reliable sealing surface for the discharge valve, while the helical springs ensure smooth valve operation and reduce wear. Built for durability and optimal performance, this assembly enhances refrigerant flow, improves compressor efficiency, and extends the lifespan of refrigeration systems.
