Flange Ball Valve

Product Introduction

The floating ball valve clamps the valve with the middle ball core in a "floating" state through two sealing rings on valve seat at the inlet and outlet. It is mainly used on pipes to cut off, distribute and change the direction of media flow. The main structural features of floating ball valve include valve seat sealing design, reliable inverted sealing valve rod, fireproof electrostatic function, automatic pressure relief and locking device‌.

Product Advantages

1. The floating ball valve sandwiches the middle ball core through the two sealing rings on valve seat at the inlet and outlet. When the ball core is closed, the semi-circular shape at the top of the valve stem and the semi-circular groove of the ball core are in the same direction, and the medium pressure pushes the ball core to move towards the outlet direction, thereby increasing the sealing performance of the outlet valve seat‌‌.‌

2. The valve seat design of the floating ball valve ensures a low friction coefficient, making the operating torque smaller and the operation more labor-saving‌.

3. The floating ball valve is equipped with anti-static device and fireproof structure to ensure safety during operation‌‌.‌

4. The valve stem of the floating ball valve is equipped with an anti-fly structure. The valve stem is bottom-mounted to prevent flying out under pressure and forms metal contact with the valve body after a fire to ensure that the valve stem is sealed‌‌.‌

5. The valve seat materials of floating ball valves include PTFE, PPL, nylon, PEEK, metal hard seals, etc., with a wide range of applications‌‌6. The floating ball valve has a compact structural design, opens and closes quickly, and can complete the opening and closing function by rotating 90 degrees. The diameter of the ball channel is the same as that of the pipeline, with small flow resistance and large circulation capacity‌‌7. Floating ball valves mainly include stainless steel ball valves, two-piece floating ball valves, carbon steel ball valves, cast iron ball valves, pneumatic ball valves, high-pressure floating ball valves, worm gear floating ball valves, and electric ball valves.

• The floating ball valve is suitable for the pressure range of 150LB ~ 2500LB, and the maximum diameter can reach 1000mm. It is especially suitable for cutting off or distribution processes in general industrial pipelines. Due to its simple structure and low cost, floating ball valves perform well in non-critical control, such as petroleum, chemical, metallurgical, natural gas, pharmaceutical, paper, printing and dyeing industries‌.

• The structure of the floating ball valve sandwiches the middle ball core through two sealing rings on  valve seat at the inlet and outlet. Turn the valve stem to drive the ball core to rotate 90 ° to realize the switching action. Under the action of medium pressure, the ball core moves to the outlet direction, thus ensuring the tightness‌.

• The main function of the floating ball valve is to rely on the medium pressure to generate displacement on the valve seat, while the valve seat remains motionless. This design allows the ball core to tightly press the outlet valve seat under the action of medium pressure, thus increasing the sealing performance‌.

• The floating ball valve is equipped with an ISO connection platform, which can meet various drive requirements, such as worm gear, pneumatic, electric, hydraulic, etc.
