Fully welded ball valves, also known as welded body ball valves, feature a valve body that is fully welded. This type of valve is mainly used to Heating and Natural Gas system, The body is made of Cod-pressing pipe,which is same to pipe line,Thus avoid uneven stress.The seat includes RPTFE and loaded spring, which can adjust seat position with change of Pressure and temperature, to achieve Zero leak.
We are manufacturers and suppliers of fully welded ball valves, offering a wide range of valve sizes including DN15 to DN200 all welded ball valves. The fully welded valve body ensures there are no external leakage paths, and it is tested to API598 standards. Welding of the valve body should undergo non-destructive testing.
Our production of fully welded ball valves includes connection methods such as RF and BW. We also customize fully welded ball valves or designs similar to Cameron fully welded ball valves, especially the Cameron T31 fully welded ball valve design.
Our fully welded ball valves are available in materials such as carbon steel ST37.0, P235GH, and 20# steel, capable of withstanding temperature ranges from -20°C to +180°C, and pressure ratings from PN16 to PN40 or 150LB to 600LB.
Our fully welded ball valves support various actuation methods including lever, worm gear, electric, and pneumatic actuators.
Fully welded ball valves characters:
1.One-piece welded body & End piece connection pipe
2. Bubble tight.
3. Pre-loaded seat springs ensure leak-tight at low pressure and reduce torque.
4. Anti blow-out stem.
5. Double O-rings ensure the stem sealing are replaceable.
6. Self-lubricating Stem bearing
7. PTFE+C / NYLON / PEEK Seat
8. Mounting Pad(If needed)
9. Extent Stem(If needed)
10.Low emission control(If needed)
