Description
The Type 51SS regulator product line is designed for service with a wide variety of corrosive gases and environments. Special construction features include 316 stainless steel for the housing and filter assemblies, with fluorocarbon 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 applications include petrochemical processing, chemical plants, food processing and paper/pulp mills.
This ruggedly built regulator operates in pressure ranges up to 150 PSIG (10.3 BAR). The Type 51SSFR and Type 51SSAR Regulators and the Type 51SSF and Type 51SSAF filter assemblies have built-in dripwells which trap water, oil and other contaminants. The contaminants are easily
flushed out of the dripwell via a convenient manual or automatic drain valve. The 40-48 Mi­cron Filter is constructed of sintered 316 stainless steel, and is easily removed.
The Type 51SS products can be through-panel mounted with the mounting nut supplied (regula­tors only), bracket-mounted using the optional bracket (regulators only), or pipe mounted by its ports (regulators and filters).
The regulators and filter assemblies comply with NACE material requirement #MR-01-75 for sulfide stress cracking resistant metallic material for oil field equipment.
Air Regulators
Type 51 SS
Pressure Regulator Series
Once set to a desired pressure, the
Marsh Bellofram Type 51 Stainless
Steel Regulators maintain their
settings permanently.
The integral convoluted diaphragm
provides constant adjustment to
downstream pressure drop,
downstream pressure increase
and changes in forward flow.
