Ball Valves

Fully

Fully Welded Ball Valve

Since the seat of the standard port fully welded ball valve?is made up of a carbon teflon seal ring and a disc spring, it is adaptable to changes in pressure and temperature and will not produce any leakage in the marked pressure and temperature range.
Fully welded ball valves are widely used in domestic steel mills, petroleum, chemical, gas, boiler, paper, textile, pharmaceutical, food, ship, water supply and drainage, energy, polysilicon, electricity and so on.
Size: 2”~40” (50mm~1000mm)
ASME Class: 150LB~2500LB
Connection Ends: Flange, Butt Weld
Operation: Lever, Gear, Electric, Pneumatic etc.
