PRESSURE REDUCING REGULATORS
PRESSURE REDUCING REGULATORS
MODEL MPRV-L The Model MPRV-L is a compact, Brass body or SST body pressure reducing regulator used to control outlet pressure up to 600 psig.
MODEL PBE-H
MODEL 4381
MODEL PBE-L
The Model PBE has a compact body and functions in a dual role as a pressure building regulator and as an economizer relief regulator in one model. The pressure build feature controls the outlet pressure while the econo-mizer feature operates to relieve any excess pressure in the system above set point from atmospheric to 250 psig.
The Model PBE-L has a compact, forged body and functions in a dual role as a pressure building regulator and as an economizer relief regulator in one model. The pressure build feature controls the outlet pressure while the economizer feature operates to relieve any excess pressure in the system above set point from atmospheric to 600 psig.
The Model 4381 duplicates the strengths of the 3381 in SST. Its high-mass plug contributes to stability and it can handle industrial gases, air, oil, steam, water, and many chemicals.
The Model MPRV-L is a compact regulator with a Max Cv of .48
The Model 4381 is a SST- bodied regulator for low-flow service.

MODEL MPRV-H
The Model MPRV-H is a compact, Brass body or SST body pressure regulator used to control outlet pressure up to 600 psig.
MODEL HP The HP is a heavy-duty high-pressure regulator designed to control downstream pressure between 10 and 750 psig with inlet pressure as high as 3000 psig. Composition seat provides bubble-tight shutoff. Metal seating is available and metal seating surfaces can be stellited. This regulator is not designed to be used in steam applications.
