A/C Pressure Relief Valves

Schrader Pacific’s Air Conditioning Pressure Relief Valve “Mini PRV” is used on the air conditioning compressor or the fluid transport line attached to the compressor. Schrader Pacific’s A/C PRVs are manufactured in a fully automated assembly cell with multiple quality assurance stations to assure that the assembly process maintains the level of quality and capability required. Each A/C PRV is calibrated to the customer’s specific set-point requirement, and every A/C PRV is tested for opening pressure, closing pressure, and leakage. The unique sealed tube packaging assures that the A/C PRV will arrive at its global destination clean and free of shipping damage. Standard opening pressure calibrations range from 350 to 600 psi with a typical tolerance of ±25 psi. Opening pressure calibrations from 125 to 1100 psi are available for special applications.

Schrader Pacific manufactures approximately 15 million A/C PRVs in the US each year, and the 300 million A/C PRVs in service will attest to the capability and reliability provided by this product. The Schrader Pacific A/C PRV is designed to meet the requirements of SAE J639 and the A/C PRV performance specification of every automotive OEM. The Schrader Pacific A/C PRV is available in either brass or aluminum construction to meet the various requirements of our customers.
