The Type 855BP is a compact relief valve that provides economical, high-performance pressure relief with an adjustable set point. It is a normally closed valve that will remain closed until the inlet pressure exceeds the regulator’s set point.
A typical application for the Type 855BP Miniature Back Pressure Regulator is to provide protection against over-pressurization in the downstream portion of a pneumatic system. In an over pressurization scenario, the air flowing through the Type 855BP can be vented to the atmosphere or could be captured and directed to trigger an emergency shut-off valve.
The Type 855BP is capable of relieving at a rate up to 35 scfm (990 Nl/min) and is available in 1/4″ NPT porting. The Type 855BP will handle a 250 psi (17.5 bar) maximum system pressure and offers five setpoint pressure ranges from 0-5 psi (0-0.4 bar), up to 0-100 psi (0-7 bar). The Push-Pull locking knob feature prevents inadvertent pressure adjustment.
