T70 BP High Flow Back Pressure Regulator Valve

The Type 70 Back Pressure Regulator functions as a high flow, high precision pneumatic relief valve with an adjustable setpoint.

The Type 70BP back pressure regulator can be used in place of a standard relief valve to improve pressure control while maintaining protection against over pressurization, as in supply pressure lines to instruments and other control devices. It is most often used in conjunction with a diaphragm-operated valve and bleed orifice as a compressor controller.

Excess compressor pressure is relieved through the back pressure regulator to actuate the intake restricting valve. When the back pressure regulator is shut off, downstream air escapes through the bleed orifice, allowing the restricting valve to open.
