The T-type three-way ball valve is a specially designed valve with a ball as its core component, offering excellent fluid control performance. This valve has three ports, allowing connection to three pipelines and enabling fluid reversal and diversion.
Its core structure consists of a four-seat sealing system and a T-shaped flow channel. Rotating the valve core allows for the interconnection of the three forward flow channels or the conduction of any two channels. The T-type valve also features media mixing and flow direction switching capabilities. Valve body materials include reinforced PTFE, stainless steel, and cast steel WCB, making it suitable for weak acid, alkali, and steam media environments, with operating pressures ranging from 1.0 to 6.4 MPa.
Actuation methods include manual, pneumatic, and electric, with a four-seat design and elastic elements ensuring sealing stability. Some models integrate a fluid velocity measurement device and a quick-release structure, improving operational efficiency and flow control accuracy.

3 Way Ball Valve T Port Working Principle
The working principle of the T-type three-way ball valve is based on the rotation angle of the ball. When the through-hole of the ball is aligned with the channel of the valve body, fluid can pass freely; when the ball rotates 90 degrees, the through-hole closes or changes the flow direction. For example:
- Diverting function: Fluid enters from one inlet and is distributed to either of the two outlets through the L-shaped through-hole of the ball.
- Merging function: Fluid enters from two inlets and merges into one outlet through the T-shaped through-hole of the ball.
- Switching function: By rotating the ball, the flow direction of the fluid can be quickly switched, suitable for systems that require frequent process changes.
3 Way Ball Valve T Port Features
- Multifunctionality: The T-type three-way ball valve has the functions of diverting, merging, and switching the direction of media flow, and can flexibly control the flow of media in complex pipeline systems.
- Reliable sealing: The seat and sealing ring of the T-type three-way ball valve are usually made of high-quality materials to ensure the valve's sealing performance.
- Easy to operate: The T-type three-way ball valve has a variety of actuators, including handle, worm gear, turbine, pneumatic and electric, which allows users to choose according to their actual needs.
- Long service life: Due to the structural design and material selection of the T-type three-way ball valve, it has a long service life.
