Product Detail:
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.

Coalescing Filter: Replaces the 40 micron filter for both moisture and particulate filtration. (Type 51SSAR & Type 51SSAF only) P/N 010-312-000
Non-Relieving: Used in applications where it is desirable to relieve pressure downstream and not at the regulator. Non-relieving regulators should not be used for low or no flow applications.
Socket Head Build Screw: Socket head build screws are provided in place of phillips drive screws.
5 Micron Filter: Replaces the 40 micron filter for more complete air filtration. (Except Type 51SSR) P/N 836-000-002
Mounting Bracket: 316 Stainless Steel bracket for side mounting. P/N 607-000-128
Pressure Gauge: Dual scale (psi / kPa) 21⁄2" (63mm) gauges. Ranges include 0-60 psi (0-410 kPa), 0-100 psi (0-690 kPa) and 0-200 psi 0-1400 kPa). When specified with regulator, the correct range will be supplied.
Tamper Resistant Cover: A 316 stainless steel hexagonal cover placed over the adjusting screw and threaded onto the bonnet of the regulator with a wrench, prevents ordinary hand adjustments.
Low Bleed Diaphragm: (Soft Relief Seat): Used in applications where it is desirable to minimize the standard bleed rate of the regulator while maintaining the ability to relieve excess pressure at the regulator. (Bleed rate is reduced from less than 6 SCFH (2.8 LPM) to less than 0.1 SCFH (0.05 LPM).
