Fully welded ball valves are widely used in many area for it has the excellent&stable working performance which general casting ball valves could reach. Fully welded ball valves are welcomed in various pipeline or devices such as in area of urban natural gas transfer and urban heat supply, petrochemical, ship building, steel, pressure regulating station, power plant and etc. This valve could be easily installed and work normally for a long period with necessary maintenance. Fully welded ball valve could be buried below the group and reduce the cost the a valve chamber(some damage would still occer in it when worker operates the valve) for general ball valves.

The welding work of the connection ends of Q61Y fully welded ball valve should be done with electro-welding or hand-welding. The connection pup shouldn't be too short to avoid over-high tempereture of the seat part to cause any potential damage to the seat sealing. The valve should be totally open when installed.

Fully welded ball valves (Flanged or butt-welding connection) are suitable for use on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN100 to cut off or allow the following of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs.

There wouldn't be any external leakage as it's fully welded. And spring loaded RPTFE(20% C reforced type) insert is used to ensure there wouldn't be any problem with the designing range both of pressure and temperature. Advanced devices are used to check the pricision of ball manufacturing

Fully Welded Ball Valve Usage:

Urban gas: Gas exporting pipeline, main pipeline and its branches.

Heat supply: Heat exporting pipe, the main pipeline and its branches.

Heat exchanger: On-off function on Pipeline and its branches.

Steel factory: all the pipelines carrying medium, waste gas, fuel, coal and heat supplying system.

Various industrial devices: various pipeline system in heat treatment, industrial coal gas and heat transfer.
