Back Pressure Regulator Introduction

Back Pressure Regulator (BPR) is a device that maintains a defined pressure upstream of itself, at its own inlet. When fluid pressure at the inlet exceeds the setpoint, the valve opens to relieve the excess pressure.


Back Pressure Regulator Feature

  • Single stage type relief structure

  • Maternal and diaphragm use hard seal form

  • The internal structure easy to purge and with filter

  • Can use panel or wall mounting

  • Line and Panel mounting pressure regulator

  • Brass chrome plated body and bonnet for non-corrosive gases and mixtures up to grade 6.0

  • Stainless steel 316L body for corrosive gases

  • Or 3 ports flexible configuration

  • Function similar to relief valve,ease of adjustment.

  • Simple outlet pressure limitation by handwheel

  • Tested for use with oxygen
