Bevel gear American Standard globe valve J541H (large diameter globe valve) Product Description:

The   opening and closing parts of the bevel gear cut-off valve are   plug-shaped clappers, the sealing surface is flat or conical, and the   valve claw moves linearly along the center line of the fluid. Stem   movement form, lifting rod (stem lift, hand wheel does not lift), there   are lifting rotary rod (hand wheel with the stem rotating together, the   nut is located in the valve body). Globe valve only applies to fully   open and fully closed, does not allow for regulation and throttling.

American   standard globe valve API and ASME standards, ASTM, ASTM is the material   standard, not the valve itself; according to the American standard   design, manufacture, production and testing of the globe valve is called   the American standard globe valve. American standard stop valve and   flange stop valve belong to the same type of valve, the closure is a   valve flap, valve stem around the centerline for rotation to achieve   open, close a valve.

 

American standard bevel gear valve J541H main advantages:

American   standard stop valve in the pipeline is mainly used to cut off,   distribution and change the flow direction of the medium. American   standard stop valve is widely used in recent years, a new type of valve,   which has the following advantages:

1, the fluid resistance is small, the resistance coefficient and the same length of the pipe section.

2, simple structure, small size, light weight.

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

4, easy to operate, quickly open and close, as long as the full turn to 90 degrees off, easy to remote control.

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

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

7, a wide range of applications, the path from small to a   few millimeters, up to a few meters, from high vacuum to high pressure   can be applied, the ball rotated 90 degrees, the entrance and exit   should be all spherical, thus cutting off the flow.
