Pneumatic Ball Valve: Features and Applications
- DELCO Valve
DELCO, as one of the leaders in valve manufacturing, not only has excellent technology and reputation in the field of pneumatic ball valves, but also sets the industry benchmark in the field of industrial automation. Let’s discuss the characteristics, working principle and wide range of applications of pneumatic ball valves.
What is a pneumatic ball valve?
Pneumatic ball valve is a ball valve with pneumatic actuator, pneumatic actuator execution speed is relatively fast, the fastest switching speed of 0.05 seconds / times, so it is usually also called pneumatic fast cut-off ball valve. Pneumatic ball valves are usually configured with various accessories, such as solenoid valves, gas source processing triplex, limit switches, positioners, control boxes, etc., in order to realize the local control and remote centralized control, in the control room you can control the valve on and off, do not need to run to the scene or the high altitude and the danger of bringing manual control, to a large extent, saving human resources, as well as time and security.
Working principle of pneumatic ball valves
Pneumatic ball valve through the compressed air, the air source to drive the ball core rotation 0-90 degrees to control the ball valve switch, according to the demand for assembly of the valve positioner, so as to control the opening of the ball valve ball core to regulate the flow of media. When the ball center rotates to 90 degree when the valve is in a tightly closed state, when the actuator works, only a small turning torque can be tightly closed the valve tightly, so as to achieve the principle of rapid cut-off cut-off.
Features of pneumatic ball valves
- Fluid resistance is small: the full diameter of the ball valve is basically no flow resistance.
- Simple structure: small volume, light weight.
- Tight sealing: with two sealing surfaces, the sealing surface made of plastic and other materials, good sealing, suitable for vacuum systems.
- Convenient operation: fast opening and closing speed, only need to rotate 90 degree to realize fully open or fully closed, easy to control from a distance.
- Convenient maintenance: simple structure, sealing ring activity, easy to disassemble and replace.
- Prevent media erosion: in the fully open or fully closed state, the sealing surface of the ball and the valve seat is isolated from the media, the media will not damage the sealing surface of the valve when it passes through.
- Widely used: diameter range from a few millimeters to several meters, applicable to high vacuum to high pressure environment; applicable to the media with suspended solid particles.
Applications of pneumatic ball valves
Pneumatic actuated ball valve is widely used in industrial automatic control systems such as petroleum, chemical, light industry, pharmacy, papermaking, etc.
- Chemical industry: piping system for conveying acid, alkali, salt, organic solvents and other fluid media.
- Petrochemical industry: fluid control of pipelines for oil, natural gas and so on.
- Food industry: fluid control of food, beverage and other industries.
- Metallurgical industry: high-temperature and high-pressure environment in the metallurgical industry, such as casting, forging, rolling and so on.
Conclusion
Pneumatic ball valves play an indispensable role in chemical, petroleum, food, metallurgy and other fields. With the continuous progress of technology and market demand continues to expand, DELCO’s pneumatic ball valves will continue to play an important role in the future development, to help various industries to achieve more efficient and safer production operations.
