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.
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
