Refrigerating Specialties A2CK Compact Reseating Relief Regulators

The A2CK pressure relief regulator is a compact, direct diaphragm operated regulator for use with ammonia, R-22, R-134a, R-502, and other common refrigerants. The design maximum rated pressure of the valve (MRP) is 300 psig (21 bar). This regulator is used in systems where a small direct operated valve is required as a safety device to relieve "trapped" liquid lines in the event that a hydrostatic pressure condition develops. The regulators are furnished with flanges for FPT: Internal NPT (USA Standard Taper Pipe Thread), socket weld, weld neck or ODS (solders over copper tubing of given external diameter) connections. The regulator can be easily removed for service. A strainer can be furnished to close couple the inlet of the regulator.
