T Port 3-way Ball Valve Description
T-type three-way ball valve is a valve that controls the connectivity of three orthogonal pipes by rotating the ball. Its flow channel is arranged in a T shape, which can realize the functions of medium diversion, confluence and flow direction switching.
Main assembly
Valve body: Forged or cast (carbon steel/stainless steel), with three flanges/threaded interfaces;
Ball: T-shaped channel design, surface hardening treatment (such as tungsten carbide spraying) to improve wear resistance;
Valve seat: Four-seat structure (standard is double valve seat) to achieve two-way sealing balance.
Working Mode
| Sphere Position | Function | Application |
|---|---|---|
| 90° Rotation | A→B or A→C Split | Chemical raw materials distribution |
| 180° Rotation | B+C→A Confluence | Oil mixing transportation |
| Specific Angle | A→B+C or Full Shutdown | Emergency shut-off |

T Port 3-way Ball Valve
Advantages
Multi-function control
A single valve can realize flow diversion, confluence and reversing, simplifying the pipeline design by 30%.
Low flow resistance and high efficiency
Full-diameter design, flow resistance coefficient ≈ straight pipe section, energy saving more than 15%.
Reliable sealing
The four-seat structure is force-balanced, and the sealing life is increased by 3 times under high temperature/high pressure.
Easy maintenance
Top-mounted structure, online replacement of seals only takes 30 minutes.
Packaging and transportation specifications
Packing requirements
DN50 and below: moisture-proof wooden box + flange protection cover;
DN50 and above: frame wooden box fixed, valve body suspended for shockproof.
Transportation label
Mark the pressure level, flow arrow and "fragile shockproof" label;
Attach material report, test certificate and API certification documents.
T-type three-way ball valve solves the core pain points of medium distribution, high temperature sealing and space limitation in complex piping systems through structural innovation and rigorous testing.
