Schischek Electric Actuator
Schischek ExRun S explosion-proof electric actuator for globe and 3-way valves.

Actuator manufacturer and flow control company Rotork has announced the acquisition of the entire share capital of the operating companies of the Schischek group. Schischek designs, manufactures and sales explosion-proof electric actuators, sensors, transmitters and controllers, principally for the heating, ventilation and air conditioning (HVAC), chemical, pharmaceutical, shipbuilding, and offshore industries.

Schischek will become part of Rotork’s Controls division and Roland Graf, the current managing director of Schischek, will remain in this position. Rotork said the acquisition increases the company’s existing range of explosion-proof actuators and provides exposure to a new end-market.

Schischek product ranges encompass rotary and linear electric actuators and control systems providing on-off and positional control for two- and three-way valves and dampers, including spring-return options. Actuator ranges are complemented by transmitting and switching sensors for differential pressure, temperature and humidity, and other accessories including door holder magnets.
Schischek products are used throughout the world and are approved and certificated by Ex, UL, CSA (both U.S. and Canada), ExGostR, and IECEx. Products are also IP66 and SIL2 rated.

Schischek has main headquarters in Langenzenn near Nuremberg in Southern Germany and Lutzenberg, Switzerland.
