【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.
