Back Pressure Regulators 

Pressure Tech

The BP-MF690G/H is a back pressure regulator for gas or liquid applications suited for typical low flow applications to 50lpm (liquid), this accurate regulator controls inlet pressure and vents excess pressure back via the threaded outlet port.

The BP-LF690 is a back pressure regulator for gas or liquid applications suited for typical low flow applications to 10lpm (liquid), this accurate regulator controls inlet pressure and vents excess pressure back via the outlet port.

Pressure Tech

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...

Pressure Tech

The BP-300 has been designed with a convoluted Inconel X750 diaphragm that lasts 50% longer than alternative stainless steel designs. Its compact simple design makes it ideal for general purpose applications, where accurate control of upstream pressure is required.
