Overview
The one-piece internal thread ball valve body is cast using advanced technology introduced from Taiwan, with a reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close; The one-piece internal thread ball valve stem adopts a bottom mounted structure with reverse sealing, and the stem will not be flushed out when the valve chamber is abnormally pressurized.
Product Details
1. How to translateApplication scope:
Internal thread ball valves and butt welded ball valves are suitable forPN1.0～4.0MPaWorking temperature-29～180℃(The sealing ring is reinforced with polytetrafluoroethylene)or-29～300℃(The sealing ring is made of para polystyrene)Used to cut off or connect media in various pipelines. Choose different materials,It can be applied to various media such as water, steam, oil, nitric acid, acetic acid, etc.
IIStructural features:
1The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2Simple structure, small size, and light weight.
3Tight and reliable, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.
4Easy to operate, quick opening and closing, from fully open to fully closed, just rotate90°Easy to control from a distance.
5Easy to maintain, ball valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
6When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7Wide range of applications, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.
