What is a fully-welded ball valve?
The ball valves are extremely reliable, absolutely maintenance-free and are particularly suited for applications in enclosed pipeline systems.
WESDOM ball valves meet all of the important approval guidelines and standards!
In general, WESDOM ball valves are manufactured for extreme requirements – as series product, as special series as well as special productions at the customer’s request.
Welded ball valves with integral welded valve bodies can effectively avoid external leakage. Welded ball valve is widely used in various fields, its superior quality and high performance stability is ordinary cast steel ball valve can not reach, all-welded ball valve service life is far greater than cast steel ball valve, all-welded ball valve is widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment.
Welded ball valves are generally available in blue, yellow, grey, black and other colours. Transmission methods include handle, turbine, pneumatic, electric, etc.

Quality Control Process
Standards&Features:
Standard：
ASME B 16.34/API 6D /API 608/BS EN ISO17292/ISO14313
Face To Face Dimensions：
ASME B 16.10/API 6D/EN558
Connection End：
ASME B 16.5/ASME B 16.47/ASME B 16.25/EN1092/JIS B2220/GOST12815
All-welded ball valve performance:
1. No maintenance, adjustment and lubrication, easy to install, reliable long-term operation at low running costs. The surface adopts spraying treatment technology, lustrous and beautiful, which has been in the leading level in China.
2. The surface is sprayed with plastic treatment technology, which has a beautiful lustre and is at the leading level in China. There will be no external leakage etc. The valve body is of welded construction, so the valve is light and easy to insulate.
3. The operating handle can be removed and installed in a different direction.
4. The valve seat is made up of a carbon fibre reinforced Teflon seal ring and a disc spring, so it is highly adaptable to changes in pressure and temperature and does not produce any leakage in the marked pressure and temperature range.
5. The processing of the ball is followed by an advanced computerised tester, so the ball is processed with high precision.
6. As the valve body material is the same as the pipe material, there will be no uneven stress and no deformation due to earthquakes and vehicles passing over the ground, and the pipe is resistant to ageing.
7. Integral fully welded, equal and variable diameter channels, fixed and floating balls, double piston effect sealing system, automatic injected sealant type bearings.
8. To prevent static electricity, the stem and ball and between the stem and stuffing box are equipped with steel balls and springs, which can keep all parts of the valve conductive to the valve body and let the current pass through the area, releasing static electricity. Not only to prevent fire, but also to prevent corrosion and to achieve a temporary cut-off for timely maintenance.
9. The stem anti-disengagement function is because the stem is affected by the pressure inside the valve and always generates a disengagement force so the stem is designed as an anti-disengagement structure.
10. Support with a low friction material thrust washer pushes the pressure against the stem so that the stem only acts as a torque transmitter.
