PRODUCT DESCRIPTION

Fully Welded 22 Inch 300LB CS A105 Side Entry Tronnion Ball Valve

The ball valve is a type of isolation valve which is the most common valve used for industry, because of its excellent operating characteristics. The ball valve can be contacted by welding, threaded and flanged, and available in a wide range of sizes, materials, temperature, pressure, and tight shutoff.
The fully-welded ball valve adopts forged material, welded body, instead of bolts and nuts, to aviod any potential leakage from body.

MAIN FEATURES:

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. 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. 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. 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 the valve body. Hence, the valve body has the same service life as the pipeline due to his special construction.
