Model 10BP Precision Back Pressure Regulator

Brand: Fairchild Industrial Products - by Rotork

The Rotork Fairchild Model 10BP Regulator is an excellent choice for applications which require high precision control of back pressures and relief pressures. The Model 10BP uses a force balance principle to open the relief valve and vent the system pressure when the set point is exceeded.

The Model 10BP features control sensitivity of 1/8" water column and a balanced supply valve to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions.

The Model 10BP pneumatic regulator is a high capacity regulator that provides greater accuracy than relief valves over a narrow pressure range, making it an excellent choice for a wide range of precision applications.

The Fairchild Model 10BP will handle a 500 psi, 34 BAR, maximum system pressure and offers nine (9) setpoint pressure ranges from 0-2 psi, 0-0.15 BAR, 0-15 kPa, up to 5-400 psi, 0.3-28 BAR, 35-2,800 kPa. The Fairchild Model 10BP back pressure regulator offers 40 SCFM, 68 m³/hr flow capacity.
