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, Burling Valve back pressure regulators are available in dome-loaded or spring-loaded models.
