Pneumatic, electric, pneumatic regulating and electric regulating types available; refer to the section on the actuator and regulating valve for details; 4. Double bearing structure with high mechanical stability and small starting torque to ensure excellent sensitivity and response speed of the valve; 5. Excellent regulating performance: the V shaped ball valve has an inherent flow characteristic similar to equal percentage and a rangeability up to 300:1; therefore, the V shaped valve can provide accurate control in a wide variation range; 6. Superior sealing performance of the metal valve seat: the V shaped ball valve has a movable metal valve seat with automatic compensation function, superior sealing performance and super long service life; from the aspect of flow direction, the leakage amount ≤10-6× rated flow coefficient; 7. Maximum flow volume: with streamline appearance and full quarter turn control, the maximum volume is very large, leading to very large flow capability and small flow resistance; therefore, a more economical and practical valve smaller in size can be used; 8. Super strong cutting capability: the V shaped ball valve is of metal hard seal structure; during rotation of the valve spool and the metal valve seat, a strong cutting force will be generated at the V notch and the valve seat, capable to cut impurities like fibers; it also has self cleaning function to avoid blocking of the valve.

Spring Return Ball Valve

The Dead man Lever Type Valve The three-piece spring automatic reset ball valve is a relatively new type of ball valve. The valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The valve stem adopts downloading structure with reverse seal, and the valve stem will not be washed out when the valve chamber is abnormally pressurized. The advantage of spring automatic reset ball valve is that it can reset automatically without manual closure, which not only saves time and labor, but also avoids the loss of medium flow. The main characteristics of spring automatic reset ball valves are small fluid resistance, simple structure, small size, light weight, compact and reliable, easy operation, convenient maintenance, three-piece ball valves are widely used in petroleum, chemical industry, urban water supply and drainage and other strict cut-off conditions. The three-piece spring automatic reset ball valve is composed of three-piece ball valve and spring handle. The main principle of spring automatic reset ball valve is that a spring handle is installed on the basis of three-piece ball valve. Its working principle is to reset automatically by triangular lever and spring compression spring. This product is also called spring automatic return ball valve, spring automatic close ball valve, spring automatic return ball valve, spring automatic return ball valve, etc. Their products all have the same function, but they are called differently.

Trunnion Mounted Ball Valve

Trunnion Mounted ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in design, and it is suitable for various corrosive and non corrosive media. Compared with floating ball valves, during operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which does not cause the ball to move towards the valve seat. Therefore, the valve seat will not bear excessive pressure. Therefore, the torque of the fixed ball valve is small, the deformation of the valve seat is small, the sealing performance is stable, and the service life is long. It is suitable for high-pressure and large-diameter situations. Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two seats that can be sealed in each direction, so there is no flow restriction during installation and it is bidirectional. This valve is generally installed horizontally.
