The pneumatic actuator has simple structure and high reliability. The response time of pneumatic actuators can often reach the millisecond level, which has a faster response speed than electric actuators, which is very advantageous in industrial automation and control applications where fast response is required. The working principle of the pneumatic actuator is to use the force of gas compression and expansion to drive the piston movement, and the material is usually metal, which makes the pneumatic actuator excellent in mechanical wear, and the service life can reach several years or even more than ten years. Pneumatic actuators are suitable for a variety of industrial fields, such as chemical, petroleum, pharmaceutical and food, especially for small and medium power mechanical equipment and automatic control systems.

Electric actuators can achieve remote control and automatic control, improve production efficiency and product quality. Valve opening and closing speed is fast and can adapt to high frequency switching and emergency cutting requirements. Valve adjustment accuracy is high, which can be applied to precision adjustment control and flow measurement. Valve seal is good, can be applied to high temperature, high pressure, corrosive media and other harsh environment. Simple structure, easy maintenance, high reliability, long service life.

Pneumatic valve adopts compact design, simple structure, easy installation and maintenance. It can be operated by pneumatic actuator, easy operation, remote control and automatic control can be easily achieved. The use of high-quality materials and manufacturing technology with high reliability and stability can adapt to a variety of harsh working environments. The use of advanced sealing technology can ensure good sealing performance and prevent medium leakage. Pneumatic valves are made of corrosion-resistant materials and can adapt to various corrosive media.

The electric valve is electrically driven, which can achieve fast switching, and can greatly improve efficiency for some occasions that require frequent switching. It is usually equipped with a variety of safety protection measures, such as overload protection, overvoltage protection, undervoltage protection, etc., which can ensure that the valve automatically stops in abnormal circumstances to ensure equipment and personal safety. The parts of the electric valve have been carefully designed and manufactured, using high-quality materials and advanced processing technology to ensure the reliability and service life of the valve. Electric valves are usually equipped with a programmable controller, which can be programmed and controlled according to the needs of users to achieve intelligent control and remote monitoring.

The structure is novel and simple, the inner diameter of the rubber sleeve is the same as that of the pipe, and the local resistance loss is small.There is no sealing point, the control medium space and the valve channel are completely isolated, and no internal and external leakage will occur. Relying on rubber sleeve deformation to achieve opening and closing, even if the fluid contains solid particles or fiber impurities will not block, can be completely and quickly closed its package. Simple structure, only three parts, can replace large volume, complex structure of the valve, especially suitable for explosion-proof requirements of the occasion.

Single flanged valves with top flanges and flanged components apply to connecting to flexible bushings.Double flanged valve, top and bottom of the same flange. The gravity casting valve body is stronger than the pressure casting valve body. The rotary valve plate is made of polymer material, resistant to wear. Fewer components, light weight, easy to handle.
