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.
