Pressure Regulators avgeerview The Refrigerating Specialties family of pressure regulators includes valves that control inlet, outlet or differential pressure. Each regulator is available with an assortment of additional variations which enable one regulator to perform several functions. 2 The 2 are compact, small capacity regulators. The 4 are heavy-duty, highflow regulators available in flanged body style in sizes 2- (¾" - 4") and weld end body style in sizes 25-2 (5" - 8"). The daptomode system makes it possible to order the regulator and modules separately for stock or field conversion. 4 2- (¾" - 4") Gauge valves and gauges may be purchased with the regulator or separately (see pages 94-95). 4 25-2 (5" - 8") 2 Port Size 4 4 4 2 2K 2-32 4-25-2 ¾" - ¼" Metal-to-Metal (PTE on 4K) Stainless Steel Lapped Metal-to-Metal Gray Iron langed 6.2-5 7.2-7.5-45 to 5-5 to 22 5 8" - 4" Lapped Metal-to-Metal Stainless Steel Lapped Metal-to-Metal Gray Iron langed 28.6-6 33.4-35 -5 to 5-6 to 22 5" - 8" Lapped Metal-to-Metal Stainless Steel Lapped Metal-to-Metal ast Steel Weld End 7-47 2-55 -5 to 5-6 to 22 Pilot Pilot Pilot See Page See Page 23-2 Seat Pilot Seat ody Material ody onnection low luid Temperature Kv v Operation ulletin for Reference Stainless Steel Lapped Metal-to-Metal Gray Iron langed.28.5-45 to 5-5 to 22 irect iaphragm 2-2 Stainless Steel Lapped Metal-to-Metal Gray Iron langed.43 (Inlet).5-45 to 5-5 to 22 irect iaphragm 2-2 Stainless Steel Lapped Metal-to-Metal Gray Iron langed -45 to 5-5 to 22 irect iaphragm 2-3 Pressure Setting Ranges Set Point Range pprox.

Pressure Regulators Pyap T gee 2K Relief Regulators ompact, direct diaphragm operated Maximum rated pressure (MRP): 27.6 bar (4 PSIG) langed connections: PT, SW, WN, OS vailable with close coupled strainer escription The 2K pressure relief regulator is direct diaphragm operated, for use with refrigerant liquid or vapor. The regulators can be used with aonia, R-22, R-34a, R-57 and other coon refrigerants. 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 2K should not be piped or applied as SME certified safety relief valve for use on pressure vessels. The 2K utilizes a special pilot seat designed to provide for a higher flow rate (v) than the 2K relief regulator. dditionally, with a relatively small ratio of diaphragm to pilot seat area, it is designed to open and regulate refrigerant flow quickly through the pilot seat once its set point has been reached. The design of the valve allows for this "quick release" feature. owever, it does not offer the same type of controlled response which may be required for a standard regulator application. or those applications where a small regulator is needed for accurate upstream pressure control, an 2 or 2 direct operated regulator should be considered.
