The West Virginia-based manufacturer of OEM, industrial and process control instrumentation, Marsh Bellofram Corporations Type 52SS family of NACE-compliant stainless steel gas pressure regulators and filter is specifically designed for use within a variety of sour gas, high-corrosion and other severe environments. The regulators are offered with a range of available port sizes, from ¼ up to an industry-exclusive 1 NPT. The specialty construction features a 316 stainless steel housing and filter assemblies, with fluorocarbon elastomers used for the control diaphragm and supply valve. The Type 52SS operates over pressure ranges of up to 150 psig (10.3 bar), with excellent stability, repeatability and low droop.
Type P52SSFR and P52SSAR regulators along with Types P52SSF and P52SSAF, have built-in dripwells to trap water, oil and other contaminants. Contaminants are easily flushed from the dripwell via a convenient manual or automatic drain valve. In addition, their easily removable 40- to 48-micron filter is constructed of sintered 316 stainless steel. Units also feature a tapped vent for ease of exhaust gas capture. Typical applications include petrochemical processing, chemical plants, food processing and paper/pulp mills.
