GQ347H orbit characteristics of ball valve products
1, the opening and closing without friction.This function completely solve the traditional valve for sealing surface friction each other and affect the sealing problem
2, the structure of the jacket type.The valve can be directly mounted on the pipeline on-line inspection and maintenance.Can effectively reduce the parking device, reduce the production cost
3, single seat design.To eliminate the influence due to abnormal pressure valve lumen medium use safety problems
4, low torque design.Special structure design of the valve stem, only with a small hand wheel can be easily opening and closing of the valve
5, wedge seal structure.Valve by valve stem provides mechanical force, wedge pressure the ball into the seat and seal.The valve sealing performance is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee
6, the structure of the sealing surface of self-cleaning.When the ball tilting away from the seat, the pipeline flow experience along the sphere seal face into evenly through 360 ¡ã.Not only eliminates the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
