Are designed primarily to work with control valves — two-way or three-way with a stroke of 55 mm and a maximum force of the rod up to 2.5 kN. They give the possibility of automatic control of the expenses of liquids or gases passing through pipelines.
Electric actuators complete with control valves are widely used for automation of greenhouses, pumping stations, processing processes, cannery climate systems, etc. as They apply to work with regulators and for manual remote control.
CONDITIONS
Designed to work under the following conditions:
