The main card for valve electric acuator RJ-80 is an important accessory for electric acuator.

RJ partial rotation valve electric device, also known as partial rotation electric actuator, partial rotation electric actuator, partial rotation electric device, abbreviated as Q-type electric device, is a driving device for valves and similar equipment to achieve opening, closing, or regulating control. Applied in industries such as power, metallurgy, petroleum, chemical, food, papermaking, pharmaceuticals, water plants, and sewage treatment, suitable for butterfly valves, ball valves, plug valves, and similar equipment that perform 90 ° rotation. If a bracket is added, it can be used as an angle stroke electric actuator, such as for air doors, baffle doors, flue gas baffle doors, and similar equipment.

 

The  valve electric acuator has the following characteristics:

1. Small in size and light in weight, the main transmission adopts a one-stage spur gear, a one-stage worm gear, and a one-stage planetary reduction mechanism with small tooth difference. The three-stage reduction mechanism is placed in the same housing and has a compact structure

2. The entire machine casing is a sealed structure, and all joints of the casing are sealed with O-ring rubber seals. This product comes in general, non-invasive, non opening cover integral, adjustable, explosion-proof and other structural types.

3. The parts that bear the load are made of high-strength materials, which have been heat treated and have high strength, and the overall load-bearing capacity of the machine is large.

4. It is equipped with travel control mechanism, torque control mechanism, on-site opening indication mechanism, Potentiometer and manual mechanism for remote indication of valve opening. Function * * *, complete machine.

5. The manual and electric switching is fully automatic, without a switching handle, users do not need to worry about operating errors caused by forgetting to pull the switching handle.

6. The large junction box has two sealed cable entry holes, making wiring very convenient.

7. There are two mechanical limit screws (one in the opening and closing directions) on the box.

8. Easy installation, adjustment, and maintenance.
