Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped core and the metal seat of the hard alloy surfacing. It is especially suitable for fibers and tiny solid particles. And other media.
Cryogenic ball valve apply to low temperature work condition that with -40℃~-196℃ medium generally , such as liquefied natural gas(LNG), liquefied petroleum gas (LPG),liquefied oxygen,liquefied hydrogen ,air separation industry and so on.The special design construction of cryogenic ball valve make valve running well under extreme condition.

The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.

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.
Metal seat ball valve apply to some special medium that consist of sands or granule,and working condition is high temperature & pressure generally.The seat material include stellite,tungsten carbide coating,Ni 60 and so on,metal seat ball valve with better wear-resisting property and more longer service life normally.

The top-entry ball valve can be disassembled on the pipeline easily and quickly, and the maintenance is more convenient and quick. When the valve break down and should to be repaired on the pipeline, it is not necessary to disassemble the valve from the pipeline, just remove the middle flange bolts and nuts, remove the bonnet and stem assembly from the valve body, and then replace the fail parts. This maintenance saves time and minimizes losses in production.
