ac compressor safety valve factory

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.

Internal pressure relief valves (IPR) are compressor safety devices that limit the maximum operating pressure of the compressor. Valves are designed in accordance with individual country code requirements, and are set to open at specific settings when the high side to low side differential pressure has been exceeded.

When the valve opens, high side pressure is relieved to the low side and once equalized the IPR valve will reseat. When evaluating compressor problems, it is important to note that small amounts of system contaminants may become trapped in the relief valve seat area, potentially allowing some high to low side leakage within the compressor.

Designed primarily for use on liquid receiver applications above the liquid refrigerant level (it is recommended that the factory be consulted before the valves are used on ther applications)

Satisfy ASHRAE Standard 15 code requirements for a refrigerant vessel safety device (Application information can also be found in ASHRAE Guide and Data Book)
