These single and two-stage positive-seal regulators features convoluted, stainless steel diaphragms that provide maximum sensitivity, minimum droop, and a leak-tight bonnet seal. Type 316 stainless steel internal components are ultra-sonically cleaned and electro-polished to a 15-Ra surface finish for applications where a contamination-free flow stream is critical.

A rugged, mechanical linkage connecting the diaphragm and valve stem significantly reduces the possibility of pressure creep. A PCTFE seat provides a 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.
