GQ47H Track ball valve Product Overview:
Baigang valve group production sales GQ47H track ball valve valve group compared with the traditional ball valve, floating or fixed sphere and valve seat contact all the time, switching torque, the sealing surface is easy to damage, the red ball valve in the opening and closing valve orbit, sphere deflection - the delta Angle first, and then turn, switch sphere and valve seat during the whole process from, so the seat will not be scraped, and open-close torque is small.Suitable for petrochemical, liquefied petroleum gas storage, refineries, natural gas, compressor systems, oil and gas pipeline, light industry, textile and other industries.
GQ47H Track ball valve Features:
(1) Open and close without friction. This feature completely solve the traditional valve seal surface friction between the impact of sealing problems
(2) the body structure. On the pipeline installed on the valve can be directly online inspection and maintenance. Can effectively reduce plant parking, reduce production costs
(3) single seat design. Elimination of the valve cavity medium due to abnormal pressure and affect the safety of the problem
(4) Low torque design. Special design of the stem, just with a small hand wheel valve can easily open and close
(5) wedge seal structure. Valve is provided by the stem of the mechanical force, the ball wedge pressed to the seat and sealed. So that the sealing performance of the valve from the impact of pressure changes in the pipeline under various conditions have a reliable sealing performance
(6) self-cleaning sealing surface structure. When the ball is disengaged from the valve seat, the fluid in the pipeline will pass through the ball sealing surface 360 ° evenly. Not only eliminates the high-speed fluid on the seat of the local erosion, but also washed away the sealing surface of the accumulation of objects to achieve self-cleaning purposes.
