forged steel ball Industrial Valves is cast into the valve, the general casting valve pressure levels are relatively low ( Such as PN16, PN25, PN40, but also have high pressure, can go to the 1500 lb, 2500 lb) And most of them are for (above basis. That forging valve forging, are generally used in high grade pipeline, the relatively small caliber, usually under (. Cast steel ball Industrial Valves opening and closing ( A sphere) Driven by the valve stem, and around the axis of rotation movement of the valve stem. Mainly used for truncated or on line in the medium, can also be used for regulation and control of the fluid, including hard seal v-shaped ball valve the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.

general component is ball valve handle ball valves, pneumatic ball valves, electric ball valves, cast iron ball valve, stainless steel ball valve, the copper ball valve, etc. Ball valve is love by rotary valve to keep the valve open or occlusion. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries.

cast steel ball valve standards:

1. Product standard

'general valve flange and butt welding of steel ball valve,' GB/T12237 - 89

iron and copper ball valve, GB/T 15185 - 1994

the general requirements of steel valves GB/T 12224 - 2005

the ShuPeiShui equipment and protective materials for domestic and drinking water safety evaluation standard 'GB/T 17219 - 1998

2。 Engineering standard

the building water supply and drainage and heating engineering construction quality acceptance standard 'GB - 50242 2002

'ventilation and air conditioning engineering construction quality acceptance specification' GB - 50243 2002

cast steel ball valve:

1. Fluid resistance is small, its resistance coefficient with section of equal length.

2。 Simple structure, small volume, light weight.

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

4。 Easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control.

5。 Convenient maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.

6。 In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.

7。 Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
