The Model 2171 is a stainless steel back pressure / relief regulator designed to handle small to mid-capacity flow rates in general, chemical or cryogenic services. This unit is capable of controlling inlet pressure to setpoint levels between 5 and 500 psig (.34 and 20.6 Barg).

Model C-PRV* is a 316L SST self-contained pressure reducing gas regulator designed for liquid or gaseous fluids utilized in sanitary biotechnological process piping systems. The unit is capable of controlling outlet pressure between 2-125 psig (.14 - 8.6 Barg) with a maximum inlet
pressure of 175 psig (12.1 Barg).

Model 123-1+6+S is a “high pressure variation” of the basic
Model 123-1+6 differential back pressure relief liquid & gas regulator.
Inlet pressure may be as high as 1500 psig (103 Barg). Differential
pressures may vary from 15–350 psid (1.03–24.1 Bard) in sizes
through 1” (DN25), and from 10–230 psig (0.7–15.9 Bard) for
size 1-1/2” (DN40). Model 123-1+6+S is NOT available for body
size 2” (DN50).

FEATURES
• High pressure operation.
• NACE or Non-NACE constructions.
• Anti-blowout adjusting screw assembly with closing cap.
• Standard non-asbestos gaskets.

APPLICATIONS: Most commonly applied to develop a constant differential pressure across a rotating shaft seal, providing proper sealing and lubricating conditions over varying pressure ranges. It may be applied in liquid or gaseous services.

A differential back pressure relief liquid and gas regulator operates in accordance with specific parameters. Sometimes called “tracking” regulators, a differential back pressure liquid and gas regulator always has the P1 – Inlet Pressure greater than the P3 - Loading Pressure by a relatively constant pressure differential – determined by the range spring. If P3 decreases by 15 psig (1 Barg), then P1 will also decrease by the same 15 psig (1 Barg). If P3 increases by 29 psig (2 Barg), the P1 increases by 29 psig (2 Barg). Thus, P1 “tracks” P3, with the differential pressure between P3 and P1 being relatively constant at DPDiff, as determined by the range spring set pressure.
