BEIER Floating Ball Valve-GYR52300 Series

The non-metallic PTFE seat ensures low friction, reduced operating torque, and outstanding chemical resistance. It is suitable for handling most corrosive media.Upon closing, the ball rotates to a position perpendicular to the pipeline, and the line pressure forces the ball against the downstream seat, providing bubble-tight sealing performance.

For the R-51300 O-type floating ball valve, under normal operating conditions, the valve seat tightly contacts the ball to ensure reliable sealing performance. In the event of a fire, when the PTFE seat is damaged or destroyed, the medium pressure continues to push the ball forward, enabling direct metal-to-metal contact between the ball and the metal seat, thereby maintaining sealing performance and achieving a fire-safe function.

The non-metallic PTFE seat ensures low friction, reduced operating torque, and outstanding chemical resistance. It is suitable for handling most corrosive media.Upon closing, the ball rotates to a position perpendicular to the pipeline, and the line pressure forces the ball against the downstream seat, providing bubble-tight sealing performance.

The metal seat is designed with an elastic sealing ring and hard-faced with Co-Cr alloy for superior wear resistance. It ensures reliable sealing under both low and high pressure conditions by automatically adjusting the contact area between the seat and the ball.An O-ring at the seat periphery provides additional sealing security. This design is particularly suitable for applications involving particle-laden media and moderate temperatures.
