The ball valve is mainly used for emergency cut-off, distribution and change of the flow direction of the medium in the pipeline. The ball valve is a new type of valve that has been widely used in recent years.

Advantages:

1. Rising stem ball valve.the valve stem is first lifted to separate the valve ball from the valve seat, and then the valve stem drives the valve ball to turn to the open position; when the valve is closed, the valve stem drives the valve ball without touching the seat.

2. The ball valve adopts a ball valve with a fixed pivot structure to ensure quick opening and closing of the valve, low torque, and easy opening and closing.

3. The valve body structure adopts a top-mounted design.

4. The valve has long-term and continuous tight sealing characteristics.

5. The valve ball sealing surface and the valve seat sealing surface adopt a frictionless design to ensure the long life of the valve sealing body.

6. The valve seat is embedded into the valve body by mechanical interference cold pressing, and the valve seat is not installed by welding, threading or adhesion.

7. The cut-off ball valve has a valve seat free scouring design.

8. The sealing surface of the valve ball adopts nickel-based cemented carbide, Hastelloy or other alloy surfacing welding, the tightness and long sealing life of the valve under the most demanding conditions.

9. The valve has two-way sealing capability and can withstand two-way pressure difference.

10. The fire-resistant design of the valve

11. The valve stem of the valve forms a continuous electrical circuit between the stem nut, bonnet, valve body, and ball core, which achieves an anti-static effect.

12. In order to improve the reliability, safety and sealing ability of the valve, and reduce the failure rate, the low pressure air tightness of the valve does not rely on the valve seat spring to achieve.

13. The position of the valve stem and the valve ball is controlled by the cooperation of the valve stem guide pin and the valve stem cut-off.

14. The installation size of the valve is the same as the existing valve, and it has good interchangeability.
