Full Welded Ball Valve Application:
Full welded ball valve can be used for following pipelines:
1. City Fuel Gas supplying: Gas output pipeline, trunk pipeline and separate regional supplying pipeline
2. Central heating system: Large heating equipment output pipeline, trunk pipeline and feeder.
3. Heat Exchanging system: Piping and the opening and closing of each circuit.
4. Steel mills: All kinds of fluid pipes, exhaust pipes, fuel gas and heat supplying pipes, etc.
5. Various Industrial equipment like heating treatment pipeline, industrial gas and heating supplying pipeline, etc.
Full Welded Ball Valve Characteristics:
API6D FULL BORE BALL VALVE full welding type A352 LF2 BODY 300LB BW 16INCH
1. One Piece Fully welded ball valve won't have external leakage problem. Fully welded ball valve seat is made of Carbon Fiber reinforced Teflon seal and Clip Spring, which can be adaptable to the changes in pressure and temperature, and it won't cause any leakage within the applicable pressure and temperature range.
2. Valve Body material is the same as Pipe material, which won't cause uneven stress from medium. It won't cause deformation because of earthquake or vehicle passing through it.
3. Undergrounded fully welded ball valve or embedded fully welded ball valve can be buried underground directly, thus,it's unnecessary to build high and large valve well, small valve well is enough, which greatly reduced construction cost and project time.
4. Ball Valve Length and Stem Length can be adjusted according to exact construction or design requirement.
5. The machining accuracy of Valve Sphere or ball is very precice and can be operated conveniently.
6. Compared to other ball valves with the same specification, Fully welded ball valve is with small body, beautiful shape and long service life.
Fully welded ball valve installation:
1. All the Steel fully welded ball valve ends welding should adopt Electro welding or Handwelding.
2. During welding, valve Chamber Overheating problem should be avoid.
3. Welding end distance to valve seat shouldn't be too short, in case the welding heating damaged the sealing ring.
4. Valve should keep open during installation.

Other remarks 1 The valve seat is embedded with flexible seal ring for zero leakage of seal; the valve seat is provided with a preloaded spring that is adaptive to the variation of pressure and temperature, so leakage is not liable to happen.
Other remarks 2 Integral valve with welded valve body, free of external leakage, etc.
Other remarks 3 Fire resisting construction of all-welded ball valve. Each leakage position is designed with flexible graphite packing or stainless steel mixing graphite to satisfy the fire resisting requirements in case of a fire.
Other remarks 4 The most advanced support plate structure both at home and abroad is adopted for large diameters to increase the service life and reduce the operating torque of valve. Thus, the service life of valves is greatly extended.
Other remarks 5 The directly-buried all-welded ball valve can be buried directly, in which case, no high and large valve pit is required, only a small shallow pit needs to be built on ground, so the construction cost and the engineering time can be significantly saved.
Other remarks 6 Full bore of valve convenient for pigging, of small flow resistance and high flow capacity and good flow characteristics
Other remarks 7 The valve ball can completely enclose the valve seat when the all-welded ball valve is opened, so the impurities in the medium will not be flushed to the valve seat or the packing surface of valve body. Hence, the valve body has a same service life as the pipeline due to his special construction.
