BP-301 SERIES Back Pressure Regulator
Piston Sensed for Medium Pressure Applications


The BP-301 incorporates a highly sensitive piston to control pressures up to 70bar with the lower Cv value of 0.1, and 35bar with a higher Cv of 0.5. Both designs provide accurate back pressure control on liquid or gas applications. Unlike relief valves, the set load from the spring is not directly applied to the seating area, and the piston sensor provides accurate control throughout the control range.
