Welding ball valves are widely used in different fields, its superior quality and high performance stability is out of reach for ordinary cast steel ball valve, the service life of full welded ball valve is far greater than cast steel ball valve, full welded ball valve is widely used in city gas, urban heating, petrochemical industry, shipbuilding, steel, gas station, power plants and other kinds of pipe devices.

Technical Parameter for fully welded ball valve:
Nominal Diameter: DN20~DN1400
Nominal Pressure: 1.6-4.0MPa
Applicable temperature: -40~200℃
Connection Type: Butt welded/Flanged/Threaded/ Threaded flange
Operation: Manual/with gear/electrical/worm gear/pneumatic/hydraulic
Standard: GB/T12237-2007,API6D,GOST,ASME B16.34,ISO 9001,KC,TS.
Fully welded ball valve advantages:
1. Integral seamless steel tube pressed full-auto welded without leaking outward.
2. PTFE+25% carbon fiber and disc spring feely compensating structure zero leakage.
3. Directly buried without need of a high ground well,saving the engineering cost.
4. Both valve and pipeline are made of the same material, without the condition of uneven stress.
5. Multiple connection combination , fire and electrical prevention design, using in the special working conditions.
6. Ball valve is not washed by the medium, to prevent corrosion.Fluid resistance is small, cost saving.
7. Maintenance-free for 20 years.
