Product Description

GQ47H track ball valve is suitable for petrochemical industry, liquefied petroleum gas storage, refinery, natural gas, compressor system, oil and gas transmission pipeline, light industry, textile and other industries. (GQ47H, GQ347H, GQ647H, GQ947H)

Product Features

1, no friction opening and closing. This function completely solves the problem that the sealing of the traditional valve is affected by the friction between the sealing surface
. 2, the top structure. The valve installed on the pipeline can be directly checked and repaired online. Can effectively reduce the device parking, reduce the production cost
3, single seat design. It eliminates the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure boost
. 4. Low torque design. Special structure design of the valve stem, just with a small wheel valve can easily open and close
5, wedge sealing structure. The valve is sealed by the mechanical force provided by the valve stem, and the ball wedge is pressed to the seat. The sealing performance of the valve is not affected by the change of pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions
. 6. The self-cleaning structure of the sealing surface. When the ball tilts away from the seat, the flow in the pipeline will pass evenly along the ball sealing surface into 360°. Not only eliminates the local erosion of high-speed fluid on the seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
