DREHMO Standard (Electric Valve Acturator konventional)

Product Description

Multi-turn actuators for on-off duty D The design principle of multi-turn actuators is to turn a multiple of **0 degree at its output-drive. DREHMO multi-turn actuators are designed to operate valves from 2 to ***0 revolutions per stroke. Within this range, the position indicating devices, like limit switches and the electronic position transducer could be adjusted. Multi-turn actuators are fitted mainly to valves, which transform the rotation of the actuator´s output drive via a threaded bush into a linear movement, which is typically for gate valves and globe valves. Multi-turn actuators for on-off duty (short time operation S***0/*5 min.) mostly operate valves with only a few open-close-cycles per month. Flanges and output-drives of the multi-turn actuators are standardized by DIN ISO ***0 or DIN ***0 respectively and therefore fit to any modern valve design. Special output flanges for DREHMO actuators are available on request. DREHMO multi-turn actuators are destinguished according to their rated torque into three housing sizes: up to *0 Nm: D *0, *9 *0 Nm to **0 Nm: D *0, **0, **9 **0 Nm to ***0 Nm: D **0, **0, ***0
