Self-acting, medium-operated proportional controller, which through automatic opening (SAVA and SAF/VFU 21) or closing (SAVD and SAF/VFG 21) of the valve prevents exceeding pressure before the valve (SAVA and SAF / VFU 21) and behind the valve (SAVD and SAF / VFG 21). The actuator features two diaphragms, which enable the valve to open in case of a defect at the control diaphragm. The controller is mainly used in district heating systems.
