BACK PRESSURE REGULATORS
PRESSURE REDUCING REGULATORS AND BACK PRESSURE REGULATORS
MODEL CA5/SA5 Models CA5 and SA5 are high performance spring- operated, flow-to-open back pressure regulators with an internal pressure balancing piston-cylinder that provides medium flow capacity and high pressure drop capability.
The Models PA1 and PL1 are stainless steel pressure reducing regulators designed to handle small to mid- capacity flow rates in sanitary biotechnical process piping systems. MODEL PA1/PL1

MODEL C-BPV
MODEL 3171
Seat-316L SST Diaphragm-EPDM
The Model C-BPV controls inlet pressures in liquid and gaseous (non- steam) applications. Its range of set pressures is from 2 to 125 psig, and its maximum operating temperature is 300° F. Optional diaphragms, plugs, and stems are made from FDA- approved materials. Model C-BPV is also 3A-approved.
Model 3171 is designed to handle low to mid-range flow rates. It can control inlet pressure to set point levels between 5 and 200 psig. Stainless steel body construction from 316 barstock virtually eliminates porosity and corrosion.
