The difference between T-type, Y-type and basket valve

Full analysis of structure, performance and application of T / Y / Basket Strainer Valve

T-type, Y-type and basket Strainer valve are common filtering devices in industrial piping systems. They have significant differences in structure, application and maintenance. The following is a detailed analysis of the differences between the three: 

1. Structural design

Y-type Strainer Valve

- Shape: It is in the shape of the letter “Y”, and the inlet and outlet are usually at an angle of 45° or 60°.

- Internal structure: The filter is located at the branch, and impurities are intercepted on one side of the filter when the fluid passes through.

- Features: Compact structure, suitable for pipelines with limited space.

T-type Strainer Valve

- Shape: Symmetrical “T” shape, the inlet and outlet are in the same line, and the filter cavity is perpendicular to the flow direction.

- Internal structure: The filter is located in a vertical cavity, and the fluid needs to turn to pass through the filter.

- Features: Symmetrical design is suitable for bidirectional flow, commonly used in steam systems.

Basket Strainer Valve

- Shape: Cylindrical shell with a basket filter inside.

- Internal structure: The filter basket has a large surface area, impurities are deposited in the basket, and can be disassembled for cleaning.

- Features: Large filtration area, suitable for large flow scenarios.

2. Filtration performance

Filtration area and pressure drop

- Y-type: Small filtration area, high pressure drop, suitable for small flow.

- T-type: Medium filtration area, pressure drop between Y-type and basket type.

- Basket type: Largest filtration area, minimum pressure drop, suitable for large flow and low resistance requirements.

Filtration accuracy

- Y-type and T-type usually Strainer Valve medium particles (such as 0.5-5mm), while basket type can handle larger particles (such as 1-10mm), but the accuracy depends on the density of the filter mesh.

3. Application scenarios

Y-type Strainer Valve

- Applicable scenarios: Protection before pumps, valves or instruments, pipelines with narrow space (such as air conditioning water systems).

- Medium: liquid or gas, such as cold water, compressed air.

T-type Strainer Valve

- Applicable scenarios: steam pipes, two-way flow systems, or locations that require horizontal/vertical installation.

- Medium: high-temperature steam, viscous liquids (such as oil).

Basket Strainer Valve

- Applicable scenarios: large-flow circulation systems (such as cooling water, sewage treatment).

- Medium: liquids containing a large amount of impurities (such as industrial wastewater).

4. Maintenance and installation

Installation complexity

- Y-type: simple, pay attention to the flow direction mark.

- T-type: flow direction needs to be considered, and symmetrical design allows flexible installation.

- Basket: usually installed vertically, and operating space needs to be reserved.

Maintenance convenience

- Y-type/T-type: the housing needs to be removed to clean the filter screen, which is suitable for intermittent maintenance.

- Basket: the cover can be quickly opened to remove the filter basket for cleaning, which is suitable for frequent maintenance scenarios.

5. Other factors

- Cost: Basket type is usually more expensive, while Y type is economical.

- Pressure resistance: Y type and T type may be more resistant to high pressure due to their compact structure.

- Durability: Basket type filter is easy to replace and has a longer overall lifespan.
