Product introduction

The stainless steel ball valve has a floating ball valve and a trunnion ball valve. The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing surface of the outlet section to ensure the sealing at the outlet end. The floating ball valve has a simple structure, compact design and good sealing performance. The sealing surface and the ball valve are often closed, and are not easily eroded by the medium. It is suitable for general industrial media such as water, solvent, acid and natural gas, and is also suitable for relatively harsh working conditions. Medium such as oxygen, hydrogen peroxide, methane and ethylene. Floating ball valves mainly include cast steel two-piece floating ball valve, forged steel two-piece floating ball valve, forged steel three-piece ball valve and one-piece cast floating ball valve. According to the sealing material, it can meet the working environment of -29 to 250 degrees Celsius. Users can choose full diameter or reduced diameter structure according to requirements. The full-bore valve flow hole is consistent with the inner diameter of the pipeline to facilitate pipeline cleaning. Stainless steel ball valves also have large diameter stainless steel ball valves, caliber 2" ~ 48", pressure range: 150LB ~ 2500LB fixed ball structure, named trunnion ball valve, can meet the needs of higher pressure and temperature.
