American Standard stainless steel flange globe valve J41W

The flow direction American Standard cut-off valve in the pipeline is mainly used for cutting, distribution and change of medium. American Standard cut-off valve is a new valve widely used in recent years, it has the following advantages:

1 fluid resistance is small, and its resistance coefficient is equal to the length of the pipe section.

2 simple structure, small size, light weight.

3 close and reliable, the current valve sealing surface material widely used plastic, good sealing, in the vacuum system has also been widely used.

4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5 easy maintenance, valve structure is simple, seals are generally active, demolition and replacement are more convenient.

6 in the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the medium through, will not cause erosion of the valve sealing surface.

7 a wide range of applications, from small to a few millimeters, up to a few meters, from the high vacuum high pressure can be applied, when the ball rotates 90 degrees, in the inlet and outlet should be all the spherical surface, thereby cutting off flow.

1, open and close without friction. This feature completely solve the traditional [wiki] valve [/wiki] sealing surface due to friction between each other and affect the sealing problem.

2, mounted structure. The valve installed on the pipeline can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs.

3, single seat design. The problem that the medium in the valve cavity is affected by the abnormal boost is eliminated.

4, low torque design. Special structural design of the stem, just with a small hand can easily open and close the valve.

5, wedge-shaped seal structure. The valve is provided by the mechanical force of the stem, the ball wedge pressure to the valve seat and seal, so that the valve seal is not affected by the pressure difference in the pipeline, in a variety of operating conditions have a reliable guarantee of sealing performance.

6, sealing surface self-cleaning structure. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

Such valves installed in the pipeline to the level of
