The ball valve with a fixed sphere does not move with the medium pressure. The ball valve with an ear shaft has a floating seat that moves with the medium pressure to secure the sphere and the sealing ring, ensuring the reliability of the seal. The top and bottom shafts can be equipped with bearings to reduce the operating torque. This design is widely used in high-pressure and large-sized valves. In recent years, to reduce operating torque and improve sealing reliability, lubricated ball valves have been adopted. Special sealing agents are injected between the sealing surfaces of the lubricated ball valves to form a protective layer. This not only enhances the sealing reliability but also reduces the operating torque, which is particularly beneficial for high-pressure and large-sized ball valves.
● Spherical Support Seat Design: The fixed ball design ensures the stability of the seal and the consistency of operation in high-pressure environments.
● Reducing Aperture: Optimized for fluid flow control, reducing pressure loss and ensuring efficient operation in large-diameter pipes.

Q:What is the difference between full bore and reduced bore options?
The full hole option has the same diameter as the pipe, allowing higher flow and minimal resistance, while the reduced hole option has a smaller diameter, making it suitable for smaller systems and more precise flow control.
Q:What is the expected service life of this valve?
The installation design combines durable materials and spring-loaded seats to help ensure the valve is performed effectively over a long life. Proper maintenance and regular inspection can significantly extend its operating life and even under high and high temperature conditions.
Q:How do full bore and reduced bore valves affect fluid flow?
All-bore valves allow minimum flow resistance and high flow capacity, making it suitable for applications that require large amounts of fluid through minimum pressure drop. Drop-hole valves are used for more precise flow control in systems that require space limits or low flow capacity.
