API 6D fully welded ball valve of 2"-56" CL150-2500 CS and SS ball
valve
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.

| Operation method | Handle, worm, motor-drive unit, pneumatic drive unit |
| Application fields | Oil and natural gas pipelines, and urban gas pipeline |
| Other remarks 1 | The 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 2 | Integral valve with welded valve body, free of external leakage,
etc. |
| Other remarks 3 | Fire 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 4 | The 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 5 | The 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 6 | Full bore of valve convenient for pigging, of small flow resistance
and high flow capacity and good flow characteristics |
| Other remarks 7 | The 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. |
