810 series electric actuators can provide a reliable position control of quarter-turn applications such as butterfly, ball valves, especially the valves of building automatic system.
Characteristic
810 series are designed with an outstanding structure and concise, meticulous appearance.
810 series are more lightweight for the die-casting aluminum case.
The protection grade reaches IP68 by using the rubber sealing ring in all jointing surface.
The two-stage worm gear and worm driving ensures 801 series operating smoothly and quietly.
Some unique designs such as the tridimensional valve position indicator and the spring-return and concealed hand/auto switch make 801 series products easier to operate.
Standard Unit(Provide motor, limit and torque switch.) Open/Close type with control package (Integrates reversing starters, protection elements, logic elements, in/output unit in an watertight box.) Folomatic control unit (Add servo operation unit base on open/close type to process the 4~20mA in/out put signal.)
Options
The VPT module could be provided to feed 4~20mADC analog signal proportional to valve position.
