Products Description
Manual Three-Way Ball Valve is a valve device that controls the flow direction, diversion, or merging of media between three pipelines by rotating a handle to turn the ball inside the valve body. Its core component is a ball with a three-way port, which can quickly alter the flow path with a 90-degree rotation. Known for its compact structure, flexible operation, and reliable sealing, it is widely used in industrial scenarios requiring multi-channel flow control.
Core Features
Flexible Flow Path Design with Diverse Functions
L-Port Flow Path: The ball features an "L"-shaped channel, connecting only two perpendicular ports (e.g., A→B with port C closed). A 90° rotation switches the flow path (e.g., A→C). Ideal for flow direction switching, the design incorporates smooth transitions (corner radius ≥1.5× pipe diameter) to minimize flow resistance and turbulence.
T-Port Flow Path: The ball has a "T"-shaped channel, enabling three flow modes:
Diverter Mode: A→B + A→C (flow split).
Mixing Mode: B→A + C→A (flow merge).
Isolation Mode: B→C (flow blocked).
Excellent Sealing Performance for Extreme Conditions
Soft Seal: Uses PTFE, PEEK, or other polymer materials. A spring-loaded seat ensures tight contact with the ball, achieving zero leakage (ANSI Class VI compliant). Suitable for low-pressure, clean media (e.g., food, pharmaceutical industries).
Metal Seal: Features Inconel 625, Stellite alloy, or other high-temperature/wear-resistant materials. The ball is coated with tungsten carbide (0.2–0.5 mm thick) for metal-to-metal line sealing, withstanding extreme temperatures (-196°C to 650°C) and pressures (Class 2500+). Ideal for petrochemical, nuclear, and other harsh environments.
Easy Operation and Quick On/Off
Manual operation via handle or handwheel enables 90° rotation for fast, effortless switching.
A keyed stem-ball connection and bottom guide shaft prevent misalignment and sticking under high pressure.
Compact Design and Efficient Maintenance
Compared to "standard ball valve + pipe tee" setups, the three-way ball valve reduces length by 30–50%, saving space (e.g., ship engine rooms, compact piping systems).
Modular design allows easy replacement of wear parts (e.g., seats, seals) without full valve disassembly, cutting maintenance time by over 50%.

Applications
- Chemical Industry
Application: Fluid mixing, heating, cooling, and other process flows.
Advantage: The T-port flow path can simultaneously connect two raw material pipelines to the reactor inlet. By rotating the valve core, it enables single-material feeding or proportional mixing of two materials without additional valve combinations.
- Metallurgical Industry
Application: Molten metal transfer and stirring operations.
Advantage: High-temperature and corrosion-resistant properties meet extreme conditions. The metal-sealed structure withstands erosion from molten metals.
- Water Treatment Industry
Application: Raw water diversion and filter backflow regulation.
Advantage: The T-port flow path diverts part of the raw water to the filtration system while the rest returns directly, enabling flow control. The soft-seal design prevents leakage and ensures water safety.
- Food & Pharmaceutical Industries
Application: High-hygiene media control.
Advantage: Precision-machined sealing surfaces between the ball and seat minimize contamination and facilitate cleaning. Soft-seal materials comply with food-grade standards, meeting strict hygiene requirements.
- HVAC Systems
Application: Water supply/return switching and heating/cooling mode changes.
Advantage: Compact design and easy operation ensure tight sealing and precise flow control, adapting to frequent system switching demands.
- Continuous Crystallization Processes
Application: Internal material discharge and reflux control.
Advantage: The T-port flow path allows full opening or partial closing of all three channels, ensuring process continuity and stability.
