GQ47H Rail Ball Valve

Compared with traditional ball valves, track ball valves, whether floating or fixed, always have contact between the ball and the valve seat, resulting in high switching torque and easy damage to the sealing surface. When the red valve track ball valve is opened and closed, the ball first deflects -8 degrees and then rotates. During the entire opening and closing process, the ball and the valve seat detach, so the valve seat will not be scratched and the opening and closing torque is small. Suitable for industries such as petrochemicals, liquefied petroleum gas storage, refineries, natural gas, compressor systems, oil and gas transmission pipelines, light industry, textiles, etc.

Products Details

Product features:

(1) Open and close without friction. This function completely solves the problem of traditional valves affecting sealing due to friction between sealing surfaces.

(2) Top mounted structure. Valves installed on pipelines can be directly inspected and repaired online. Can effectively reduce device shutdown and lower production costs.

(3) Single seat design. Eliminated the problem of abnormal pressure rise in the chamber medium of the valve, which affects the safety of use.

(4) Low torque design. The valve stem with a special structural design can be easily opened and closed with just a small handwheel valve.

(5) Wedge shaped sealing structure. Valves are sealed by the mechanical force provided by the valve stem, which presses the ball wedge onto the valve seat. Ensure that the sealing performance of the valve is not affected by changes in pipeline pressure difference, ensuring reliable sealing performance under various working conditions.

(6) The self-cleaning structure of the sealing surface allows the fluid in the pipeline to pass through 360% of the sealing surface of the sphere when it moves away from the cigarette holder. This not only eliminates the local impact of high-speed fluid on the cigarette holder, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning.

2 piece ball valve flange end

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
