Specifically developed for booster compressors, this Vilter Guard and Seat Assembly ensures stable valve operation under elevated suction pressures. The robust seat offers superior sealing performance, while the guard protects internal components from stress and vibration. Ideal for ammonia and mixed-refrigerant systems, this assembly supports continuous-duty cycles and improves discharge control. Its booster-specific design ensures optimal alignment and extended service life in two-stage or cascade refrigeration setups.
