Fully welded ball valve of 2"-56" CL150-2500, with by pass valve


KELITE has technological research & development center, Longke valve research institute, product research & development center of Nanjing University of Technology to continuously makes new products and innovates existing products and also KELITE has gotten API 6D, API 607/API 6FA, CE, IS0 9001, IS0 14001, OHSAS 18001, TS and marine certificate. We are member of China General Machinery Industry Association Valve Branch, China Gas Association, supplier of Petro China, Sinopec China National Offshore Oil Corporation, China Huadian Corporation, China Gas Holdings, China Guodian Corporation, and etc. We are awarded Chinese reform outstanding company, one of the ten major brands of Chinese valve industry.


Kelite Valves is famous for manufacturing fully welded ball valves in China market, we have made 56”CL600 fully welded ball valves for Iran market, a special technique was performed so that post welding heat treatment is not required so soft seals will not to be damaged during the welding process to make sure the seals good performance.


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.

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.
