  The Type 51SSR regulator is designed for service with a wide variety of corrosive materials and environments. Special construction features include 316 stainless steel for the housing with Flourocarbon elastomers used for the control diaphragm and the supply valve. These corrosion resistant materials are compatible with sour gas and for use in off-shore environments. Typical application include petrochemical processing, chemical plants, food processing and paper/pulp mills.

This ruggedly built regulator operates in output pressure ranges up to 150 psi with a maximum supply pressure of 250 psi. The Type 51SSR regulator can be through-panel mounted with the mounting nut supplied, bracket-mounted using the optional bracket, or pipe-mounted by its ports. The regulator complies with NACE material requirement #MR-01-75 for sulfide stress cracking resistant metallic material for oil field equipment.
