Fixed characteristics and advantages of the ball valve
Dual function of blocking and emissions
The use of spring pre-fixed the floating ball valve seat, regardless of the valve clearance in a full-or state-wide, on the downstream side of the seat so that fluid blocked in the body cavity were stranded excretion through the relief valve.
Automatic pressure relief feature
Valve body cavity temperatures stay medium caused when abnormal boost without the adoption of safety valve, and can only function of automatic pressure relief valve, this valve to ensure the liquid medium in the transportation security is very important.
Structural fire safety
Valve have a fire safety features, its design, manufacture follow API 6FA and API 607 specifications.
Note resin sealed emergency ambulance
As a result of the foreign media or fire accidents caused by the valve seat seal failure, fat injection valve provided with the injection of resin to connect the gun's rapid, convenient and quick way to seal the valve seat sealing resin is injected into the site to alleviate the leakage.
Reliable stem sealing and low operating torque
In addition to setting the standard sealing rings, the packing gland is also set up a "O" type seal, double sealed to ensure the reliability of the valve stem seals; additional graphite packing and sealing resin so that the fire after the injection of stem leakage to minimum. Stem sliding bearings and thrust bearing so that the light valve operation.
Full Bore or reduced bore
According to the need to use the whole path or necking structure. Full Bore Valve flow aperture diameter consistent with the pipeline, the pipeline to facilitate cleaning.
Stem can be lengthened
In accordance with the needs of the installation or operation, the valve stem can be lengthened. Ball pole increases, especially for the needs of city gas, such as the laying of pipelines buried occasions. Longer stem-size determined according to customer needs.
Flexible operation
Used with a small friction coefficient and good self-lubrication of the valve seat and stem bearings, greatly reducing the torque valve operation. Therefore, even if not provided in the case of grease seal, and can ease the long-term flexibility to operate the valve.
Multi-drive and easy to automate control
Drive flexible mode of operation as necessary to choose manual, pneumatic, electric, gas-liquid interaction, such as hydraulic.
