[Basic Information]

Open The Process
1, In the closed position, the valve body by the mechanical pressure of the valve stem, pressed on the valve seat.
2, When the counterclockwise rotation of the hand wheel, the stem is the reverse movement, the bottom of the corner plane to the ball off the seat.
3, The stem continues to improve, and with the stem spiral groove within the guide pin interaction, so that the ball began to frictionless rotation.
4, Until fully open position, the stem to the limit position, the ball rotation to fully open position.
 
Close The Process
1, Turn off, turn the hand wheel clockwise, stem began to fall and let the ball away from the valve seat began to rotate.
2, Continue to rotate the hand wheel, the stem is embedded in the spiral groove on the role of the guide pin, so that the stem and the gate at the same time rotating 90 degrees.
3, About to close when the gate has been in contact with the seat without rotating 90 degrees.
4, Hand wheel rotation of the last few laps, the bottom of the stem at the bottom of the plane mechanical wedge to the compression of the ball, so that it is tightly pressed in the valve seat, to completely sealed.

 [Valve Features]

1, The valve in the middle of the pressure from the tight seal structure, good sealing performance.

2, The valve, the sealing surface of the valve seat with cobalt-based carbide welding, wear, high temperature, anti-scratch performance, long service life.

3, Stem corrosion by nitriding treatment, a good corrosion resistance and scratch resistance.

4, Anti-high temperature creep design.

5, The valve cover packing depth is reasonable, filler plus corrosion inhibitor, sealed and reliable.

6, The valve has a sealed structure to ensure that the valve is running when the valve stem will not leak.

7, The valve drive mode Manual, gear drive, electric, remote control and automation can be achieved.


[Adaptation]
 Power station gate valve (main steam gate valve) for thermal power plants, petrochemicals, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam on the pipeline.
