Three-Way T-Shape Ball Valve

The oxygen specific shut-off valve is made of high-quality silicon brass or stainless steel casting, which has the advantages of high mechanical strength, wear resistance, and good safety. Used on oxygen pipelines, it has effective explosion-proof and flame-retardant properties, eliminating unsafe factors on oxygen pipelines.

I. Overview of the T-Type Three-Way Ball Valve Product
　　 The Q45F four-seat-sealed T-type three-way ball valve features a sleek design and a compact, well-organized structure. It not only allows for switching the flow direction of the medium but also enables all three channels to connect with each other—or, alternatively, isolates any single channel while keeping the other two interconnected—providing flexible control over whether the medium flows together or splits apart within the pipeline.
1. It has low fluid resistance, with a drag coefficient equal to that of a pipe section of the same length.
2. Simple structure, compact size, and lightweight.
3. Tight and reliable with excellent sealing performance, it is also widely used in vacuum systems.
4. Easy to operate and quick to open or close—simply rotate 90° from fully open to fully closed, making it convenient for remote control.
5. Easy to maintain, ball valves have a simple design, and their sealing rings are typically removable, making disassembly and replacement convenient.
6. When fully open or fully closed, the sealing surfaces of the sphere and valve seat are isolated from the media, ensuring that media flow does not cause erosion of the valve's sealing surfaces.
7. Wide applicability—capable of handling flow rates ranging from just a few millimeters to several meters in diameter, and suitable for applications spanning from high vacuum to extremely high pressure conditions.
High-platform ball valves can be classified, according to their channel configuration, into straight-through, three-way, and right-angle types. The latter two types of ball valves are used for distributing media as well as redirecting the flow direction of the medium.

5. T-Type Three-Way Ball Valve Product Selection

When selecting, please fill out the "Specification Sheet" or specify the following:
1. If the model has not been selected before placing the order, please provide us with the following usage parameters: 1. Nominal diameter, 2. Fluid properties (including nominal pressure, temperature, viscosity, or acidity/alkalinity), and 3. Valve body and valve core materials.
2. If the design firm has already selected our company’s product model, please place your order directly with our Sales Department according to the specified model.
3. When the application scenario is critical or the piping system is particularly complex, please provide design drawings and detailed specifications whenever possible, so our experts can review and ensure everything meets your requirements.
