Home / Back Pressure Regulators

Back Pressure Regulators, also known as back flow regulators or pneumatic relief valves, are a key factor in protecting downstream equipment in a pneumatic system from over pressurization. ControlAir Precision Back Pressure Regulators are high flow, stable and highly accurate with adjustable set points. A rolling diaphragm provides the sensitivity that enables these units to vent to atmosphere in response to the slightest upstream changes.

Some common applications include:

  • Tank Blanketing
  • Pressure control for fuel cell testing
  • Pressure control in the extrusion process
  • Precision bypass valves for critical processes

ControlAir Back Pressure Regulators are used in place of a standard relief valve to provide protection against excessive build-up in supply pressure lines to instruments and other sensitive control devices. The most common application is to control the air pressure in a system supplied by a compressor. Used in conjunction with a diaphragm operated inlet restricting valve and a bleed orifice, the Back Pressure Regulators relieve excess compressor pressure while activating the intake restricting valve. When the regulator shuts off, the down-stream air vents through the bleed orifice allowing the restricting valve to open.

Some common applications include:

  • Tank Blanketing
  • Pressure control for fuel cell testing
  • Pressure control in the extrusion process
  • Precision bypass valves for critical processes
