These single-stage positive-seal regulators feature convoluted, Hastelloy® C-22 diaphragms that provide maximum sensitivity, minimum droop and a leak-tight bonnet seal. Type 316 stainless steel internal components are ultra-sonically cleaned and electropolished to a 32-Ra surface finish for applications where a contamination-free flow stream is critical. Optional 15 Ra electropolished with faceseal. A rugged, mechanical linkage connecting the diaphragm and valve stem significantly reduces the possibility of pressure creep. A PCTFE seat provides positive closure and is compatible with a wide range of mildly corrosive or corrosive gases. Each single-stage positive-seal regulator is designed with two 10 x 32 UNF-threaded body holes for bracket or panel mounting.
