Imported pneumatic ball valve
Overview of imported pneumatic ball valve
Pneumatic ball valve is a type of valve with a ball center. Pneumatic ball valves only need to use pneumatic rotation. The operation and very small turning torque can close tightly. The completely equal valve body cavity provides a straight flow path with little resistance for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing, but recent development has designed the ball valve to have the function of throttling and controlling flow. The main feature of the ball valve is that it has a compact structure, is easy to operate and maintain, and is suitable for general working media such as water solvents and natural gas. The ball valve body can be integral or combined.

Structural features of imported pneumatic ball valves
Pneumatic ball valves are composed of a valve body, a pneumatic actuator and other accessories. It is an advanced control valve with a quarter-turn structure.
The valve with excellent regulating characteristics has an inherent flow characteristic of approximately equal percentage and a high adjustability ratio. This type of valve provides precise control over a wide range of variations.
Due to its streamlined shape and full right-angle rotation control, the maximum flow volume has a particularly high maximum volume, a particularly large flow capacity, and a small flow resistance, so a smaller, more economical and practical valve size can be used.
The valve adopts a double bearing structure, which has high mechanical stability and small starting torque, ensuring the valve has excellent sensitivity and sensing speed.
Maximum Reliability (Safety) The valve body is an integral structure, which is strong and durable. Its operation is not affected by pipeline pressure and can avoid valve body leakage.
The superior sealing performance of the metal valve seat uses a movable metal valve seat, which has a self-compensation function, superior sealing performance and a long service life. In the flow direction, the leakage is rated flow coefficient.
The ultra-strong shearing capacity valve adopts a metal hard seal structure. During the rotation of the molded valve core and metal valve seat, the molded gap and the valve seat produce a powerful shearing energy to cut off fibers and other impurities, and have the ability to automatically Cleaning function to avoid valve sticking.
The pneumatic ball valve has a compact structure, is small and light, easy to install and maintain.
The pneumatic actuator adopts a piston cylinder and crank arm conversion structure, with large output torque and compact size. The actuator adopts a fully sealed waterproof design with high protection level. The cylinder block adopts imported mirror cylinder, which is oil-free lubrication, has small friction coefficient, is corrosion-resistant and has super durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft does not wear.
