3 Way Threaded Ball Valve


3-way threaded ball valves (three way ball valves with threaded connections) are mainly used for cutting off, distributing and altering the flowing direction of medium. They have distinct features like small volume, reliable sealing, simple structure and convenient maintenance. Due to high corrosion resistance, 3-way threaded ball valves are widely used in water, oil, natural gas and weak corrosive liquid.


1. Our company pays much attention to technology transformation, process improvement and structure optimization, leading high quality of three way ball valves with threaded connections.
2. KERUI has complete quality systems, such as ISO 9001:2008 certification, API 6D certification, CE certification, etc. All valves are strictly inspected before into storage, thus ensuring stability of our products.
3. KERUI has optimal after-sale service, winning a gamut of customers.


1. The sealing materials (like PTFE, PPL, and carbon fiber) characterize in good self-lubrication, low friction loss, stable property, wide range of application and excellent sealing performance. They greatly prolong the service life of 3-way threaded ball valves, reducing maintenance cost.
2. The ball of three way ball valves with threaded connections 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.
