These back-pressure regulators control the inlet pressure rather than outlet pressure. They are very similar to relief valves in operation and are actually used as relief valves in many applications requiring high sensitivity and close tolerances on crack/reseat pressure relationships. This compact series of regulators is hand-adjustable and spring-loaded. A diaphragm sensor provides precise pressure control.

Bonnet Vent Ports (with Optional Bonnet Vent adapters): Allows venting of hazardous gases in the event of diaphragm failure.
