Airgas Model C445A590 Supelcoat™ Coated Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat regulator A preset safety relief valve

A preset safety relief valve makes these regulators suitable for use only with noncorrosive gases

Round construction and elevated bottom encourage circulation of air around the can to disperse heat and reduce moisture buildup and rusting

single-stage regulators are engineered to provide precision performance

mechanical linkage connecting the diaphragm and valve stem significantly reduces the possibility of pressure creep

Airgas Model C445A590 Supelcoat™ Coated Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat regulator A preset safety relief valveThis series of 316 stainless steel two stage high purity regulators is designed for non corrosive analytical, mildly corrosive and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 01 100 psi inlet change. Convoluted Hastelloy C 22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging. The metal to metal diaphragm seal
