ControlAir, a leading manufacturer of precision pneumatic and electro-pneumatic control products, announced the new Type 855BP Miniature Back Pressure Regulator. Type 855BP is a compact relief valve that provides economical, high-performance pressure relief with an adjustable set point. The valve is normally closed and 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 protect 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 can relieve at a rate up to 35 scfm (990 Nl/min) and is available in 1/4-in. NPT porting. The Type 855BP will handle a 250 psi (17.5 bar) maximum system pressure and offers five set point pressure ranges from 0 to 5 psi (0 to 0.4 bar), up to 0 to 100 psi (0 to 7 bar). The Push-Pull locking knob feature prevents inadvertent pressure adjustment.
