The Vilter Outer Seat, Ammonia or R12 & R22 Discharge Valve with Volute Springs is a critical component in refrigeration and compressor systems. It serves as the seating surface for the discharge valve, ensuring a secure seal during the discharge cycle. Designed for use with ammonia, R12, or R22 refrigerants, it is built to withstand the pressures and temperatures associated with these substances. The inclusion of volute springs provides reliable valve operation by ensuring consistent pressure and efficient refrigerant flow, enhancing the system’s overall performance, reliability, and longevity.
