3PC Stainless Steel Ball Valve


3PC stainless steel ball valve is of full bore and threaded end, thus it is also called 3PC full bore stainless steel threaded ball valve. It is easy to open and close, just needing to rotate 90°. This 3PC ball valve is mainly utilized for cutting off, distributing and altering the flowing direction of medium. It has distinct features of small volume, reliable sealing, simple structure and convenient maintenance.


1. 3PC stainless steel ball valve is not easily corroded by medium, thus it is widely used in water, oil, natural gas and weak corrosive liquid.
2. The sealing materials (like PTFE, PPL, and carbon fiber) are of good self-lubrication, low friction loss, stable property, wide range of application and excellent sealing performance. They greatly prolong the service life of this threaded ball valve, reducing maintenance cost.
3. The ball of 3PC stainless steel ball valve is of floating type. Under the pressure of medium, the ball will generate a degree of displacement and press tightly on the sealing surface of exit end, guaranteeing sealing performance.


1. Stainless steel ball valves are ISO 9001:2008 / API 6D / CE certified.
2. Our company pays much attention to technology development, process improvement and structure optimization, leading high quality of our products.
3. All valves including 3PC ball valve are strictly inspected before into storage, thus ensuring stability of our products.
