Back Pressure Regulators
Back Pressure Regulators are designed to control upstream (P1) pressure by relieving all pressure above a set pressure from the process being controlled. The Burling Valve regulators can be configured to control the pressure of various gases and liquids accurately and repeatably. Ranging in sizes from 1/2" up to 6" flange mount, the Burling Valve pressure reducing regulators are available with dome-loaded, spring-loaded or mechanically piloted version.

What pressures can Burling work with?
Max Inlet Pressure: 3,000 PSIG (207 Barg) @ 100°F (material specific)
Max Outlet Pressure: 1,000 PSIG (68.9 Barg) @ 100°F (material specific)
