                              • With the emergency hand actuator type HNG, automatic valves with double and single-acting actuators can be manually operated at any time.

                                In the case of failure in the air or electricity supply the actuator can be operated by means of a disengageable worm drive with hand wheel.

                                A mounting kit between actuator and valve does not belong to the delivery package of the emergency hand actuator and is to be ordered separately.

                              • PRESSURE BOOSTER

                              • The pressure booster multibar doubles the torque of pneumatic actuators.
                                To double the existing control pressure takes place without additional use of energy. At control pressure above 5 bar the output pressure will be limited to 10 bar.
                                An example for only one of a couple of applications: by use of multibar a smaller actuator could be used to actuate the same kind of valve which leads to more cost efficiency.
