The Parker 102942 A82B Regulator is a pilot-operated inlet pressure regulator engineered for high-capacity commercial refrigeration and HVACR systems. Built with a 1 7.02 lb ductile iron body and brazed copper couplings, this Refrigerating Specialties valve features 1 5/8" ODF connections and a 1 5/8" port, ensuring high-flow performance with minimal pressure drop. As an "A82B" model, it includes an electric wide-opening bypass feature, allowing technicians to remotely force the valve fully open for rapid system pull-down or defrost cycles. This compact pressure regulator maintains a stable set point between 10" Hg and 400 psig, compensating for fluctuations in ambient temperature and evaporator loads. The Parker Sporlan A82B is internally equalized and designed for "sweat-in" installation without disassembly, saving significant time on the job site. Its stainless steel diaphragm and interchangeable capacity cartridges facilitate easy field service from the top of the valve, making it a reliable solution for maintaining precise suction or discharge pressure in multi-evaporator racks. Key Benefits Enhanced Control: Features an electric wide-open pilot for versatile system management during defrost or high-load conditions. Durable Construction: Ductile iron body and stainless steel diaphragms eliminate common bellows failure points. Service Flexibility: Interchangeable cartridges allow for flow revisions or capacity adjustments without removing the valve body from the line. Broad Application: Compatible with all common halogenated refrigerants in industrial and commercial settings. Precision Adjustment: Wide pressure range (10" Hg to 400 psig) handles everything from low-temp suction to high-side pressure control. Common Questions How do I adjust the set point on the A82B? Adjustment must be made with the solenoid de-energized. Turning the adjusting screw clockwise increases the pressure set point, while counter-clockwise decreases it. Use an accurate gauge at the access fitting for calibration. Can this regulator be installed in any orientation? Yes. Due to the spring-loaded solenoid plunger design, the 102942 can be mounted in horizontal or vertical pipelines, provided the flow arrow on the body matches the refrigerant direction. What refrigerant types are compatible with this valve? The A8 series is designed for use with standard high-pressure refrigerants, including R-22, R-134a, R-404A, and R-507, in commercial systems.
