The SelfAct pressure regulators are available as pressure reducing- (keeping the downstream pressure constant) and pressure relief valves (keeping the upstream pressure constant). Suitable for steam, non inflammable vapors and gases and neutral liquids.

The sturdy plug head guide minimizes vibration and wear. The valve stem is sealed by a stainless steel bellows.

Up to six adjustment ranges are available per size, depending on the mounted actuator.
Easy control point setting with the hand wheel at any time. The modular design allows the mounting of the same actuators on the reducing- and relief valves. Easy mounting with a lock-nut.
For operating temperatures above +100°C / +212°F a water filled seal tank protects the diaphragm against overheating.

The SelfAct pressure regulators are capable of operating within temperatures ranging from -10 to +400°C (14°Fto + 752°F) according to the selected material.
