fully welded body ball valves


soft seated ball valve

Fully welded ball valve of 2"-56" CL150-1500 trunnion or bearing plate design

  • Kelite Fully Welded Body Valves are used in pipelines and pumping compression stations as well as subsea applications.
  • Our welded design reduces the leakage path and makes the valves ideal for underground and subsea installations.
  • Welding of the two or three piece body parts are performed with a special technique so that post welding heat treatment is not required and soft
  • Seals are not subject to damage during the welding.
  • The extensive size range and pressure class are available in a variety of materials including Carbon, Alloy & Stainless steel suitable for general to severe service conditions.

One-piece body, full bore/reduced bore, trunnion mounted, double block and bleed, single or double piston effect, anti-blow out stem, anti-static device, fire-safe certified to API-607/6FA/ISO 10497, spring loaded Seats, sealant injection, NACE MR-01-75, NYLON, DEVLON&PEEK seat inserts, designed and tested according to ASME B16.34, BS5351,KS and API-6D.
Service Type:
• Standard Temperature: -29°C to 220°C / -20°F to 428°F
• Low Temperature: -46°C to 150°C / -50°F to 302°F
• Cryogenic Temperature: -196°C to -593°C / -258°F to -620°F
• Subsea (Shallow & Deep Water)
• Underground
• High Temperature: Above 220°C / 428°F

Other remarks 1The valve seat is embedded with flexible seal ring for zero leakage of seal; the valve seat is provided with a preloaded spring that is adaptive to the variation of pressure and temperature, so leakage is not liable to happen.
Other remarks 2Integral valve with welded valve body, free of external leakage, etc.
Other remarks 3Fire resisting construction of all-welded ball valve. Each leakage position is designed with flexible graphite packing or stainless steel mixing graphite to satisfy the fire resisting requirements in case of a fire.
Other remarks 4The most advanced support plate structure both at home and abroad is adopted for large diameters to increase the service life and reduce the operating torque of valve. Thus, the service life of valves is greatly extended.
Other remarks 5The directly-buried all-welded ball valve can be buried directly, in which case, no high and large valve pit is required, only a small shallow pit needs to be built on ground, so the construction cost and the engineering time can be significantly saved.
Other remarks 6Full bore of valve convenient for pigging, of small flow resistance and high flow capacity and good flow characteristics
Other remarks 7The valve ball can completely enclose the valve seat when the all-welded ball valve is opened, so the impurities in the medium will not be flushed to the valve seat or the packing surface of valve body. Hence, the valve body has a same service life as the pipeline due to his special construction.
