French All-Welded Ball Valve stainless steel material
Product Overview:
Fully welded ball valve is widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, regulating stations, power plants and other types of pipeline equipment. All-welded ball valve can be used reliably for a long time, without maintenance, simple installation, so that the installation of other valves more convenient.

Fully welded flange ball valve characteristics:
Welded flange ball valve, no external leakage phenomenon, because the seat is composed of carbonized Teflon seal ring and coffee spring, so strong adaptability to pressure and temperature changes, in the marked pressure and temperature range will not produce any slip. The ball processing process has advanced computer detector tracking detection, so the ball processing precision is high. Because the valve body material is the same as the pipe material, there will be no uneven stress, nor will there be deformation due to the earthquake and the vehicle through the ground, the pipe aging resistance. The sealing ring body is made of PTFE with 20%C(carbon) to ensure no leakage (0%).
