        Open the process

        1, in the closed position, the valve body by the mechanical pressure on the valve, squeezed on the seat.
        2, when the hand wheel is rotated counterclockwise, the valve stem is reverse movement, the bottom of the angular plane so that the ball off the valve seat.
        3, the stem continues to improve, and the stem of the guide groove in the spiral groove interaction, the ball began to rotate frictionless.
        4 until the fully open position, the valve stem to the limit position, the ball rotates to the fully open position.
         

        Close the process

        1, When closed, turn the handwheel clockwise, the stem begins to descend and the ball leaves the seat and begins to rotate.
        2, continue to rotate the hand wheel, the stem by the guide groove embedded in the spiral groove on the role of the valve stem and the gate at the same time rotating 90 degrees.
        3, about to close the gate body has been in contact with the seat without rotating 90 degrees.

        4, the last few turns of the hand wheel rotation, the bottom of the valve rod angular plane mechanically wedged to the ball pressure, so that it tightly pressed on the valve seat, to achieve complete sealing.


         [Valve Features]

        1, the valve cavity with self-tight pressure seal structure, good sealing performance.

        2, the valve disc, seat sealing surface made of cobalt-based hardfacing welding, wear-resistant, high temperature, anti-abrasion performance, long service life.

        3, the stem by the nitrided corrosion resistance, good corrosion resistance and scratch resistance.

        4, high temperature creep design.

        5, valve cover stuffing box depth and reasonable, filler plus corrosion inhibitor, sealed and reliable.

        6, the valve has a sealed structure to ensure that the valve stem open at run time will not leak.

        7, the valve drive mode manual, gear drive, electric, remote control and automation can be achieved.
