【First】 Product Overview:
Compared with the traditional ball valve track ball valve, either floating or fixed, the ball and the valve always contact, the switching torque, sealing surface easily damaged, red valve ball valve opening and closing, the ball deflected first - delta angle, and then turn the ball during the entire process of the valve seat from the seat, so the seat will not be scratched, and opening and closing torque is small. For petrochemical, liquefied petroleum gas storage, refineries, natural gas, compressor systems, oil and gas pipelines, light industry, textile and other industries. 
 
 【Two】 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.
