Actuator
Electric actuators, also known as electric actuators. It is a drive device that can provide linear or rotary motion. The electric actuator uses a certain driving energy and works under the action of a certain control signal.
Powerful Functions
- Electric actuators are divided into switch type, adjustable type, intelligent type, and various signal output types.
Small Size
- The volume of the electric actuator is only about 35% of similar products.
Light And Cheap
- The weight of the electric actuator is only about 30% of similar products.
Reliable Performance
- Key components such as bearings, mouthpieces and electrical components are imported brand-name products.
Beautiful And Elegant
- The electric actuator has an aluminum alloy die-casting shell, which is fine and smooth, and can reduce electromagnetic interference.
Precise And Wear-Resistant
- The worm gear output shaft is integrated with special aluminum alloy forging, with high strength and good wear resistance.
Very Small Hysteresis
- The worm gear output shaft of the electric actuator is integrated, avoiding the gap of the key connection, and the transmission precision is high.
Safety Guarantee
- Passed the 1500V withstand voltage test, F-class insulated motor, safe and guaranteed.
Simple Matching
- It adopts single-phase power supply, and the external wiring is very simple, and it can also be used as 380V and DC power supply.
Easy To Use
- No refueling, no inspection, waterproof and rust-proof, installation at any angle.
Protection Device
- Double limit, overheat protection, overload protection (optional).
Multiple Speeds
- (partial rotation angle stroke) full stroke time is 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds, 100 seconds, etc.
Anti-corrosion And Anti-rust
- The electric actuator bracket, coupling and screws are all made of stainless steel.
Intelligent Numerical Control
- Digital setting, digital setting, high accuracy, self-diagnosis, and multi-function in one machine.
Integrated Integration
- The intelligent control module is highly integrated in the electric device body, and no external positioner is required.
A Variety Of Electric Actuators Are Available
Features and benefits
Three-piece ball valve and gate valve belong to the same type of valve. The difference is that its closing part is a sphere, and the sphere rotates around the centerline of the valve body to achieve opening and closing.
The three-piece ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.
Advantages of three-piece ball valve
- The fluid resistance of the three-piece electric ball valve is small, and its resistance coefficient is equal to that of a pipe section of the same length.
- Simple structure, small size and light weight.
- Tight and reliable, the sealing surface material of the ball valve is widely used in plastics, with good sealing performance, and has been widely used in vacuum systems.
- It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
- The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.
- When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
- It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
