ADVANTAGE

Lianke Valves’ T strainers (tee strainers) provide robust pipeline protection by filtering debris like rust, weld slag, and particulates in industrial fluid systems. Designed for inline installation, these T-type strainers safeguard pumps, valves, and downstream equipment from clogging and damage, outperforming cast Y strainers in flow efficiency while maintaining cost-effective coarse filtration.

Why Choose Lianke T Strainers?

Durable Construction: Available in carbon steel, stainless steel (304/316), and alloy variants for corrosive or high-pressure environments.
Easy Maintenance: Removable screen baskets simplify cleaning without pipeline disassembly.
Compliance: Meets ASME B16.34, ANSI, and DIN standards for seamless integration.

Three Configurations:
- Straight-Through T Strainers: Installed in straight pipelines for high-velocity flows.
- Forward Baffle T Strainers: Filters media inside-out (mesh inside baffle), ideal for horizontal 90° bends.
- Reverse Baffle T Strainers: Filters media outside-in (mesh outside baffle), suited for vertical or angled pipelines.
Optimized Flow Design: Reduced pressure drop compared to Y strainers, handling higher flow rates with minimal turbulence.
Filtration Precision: Coarse filtration (40-100 mesh) for protecting equipment without compromising system velocity.

OTHER PINCH VALVAS

Weir type rubber lined diaphragm valve

A weir-type diaphragm valve is a specific design of diaphragm valve that features a raised lip or saddle in the valve body. The diaphragm comes into contact with this weir to form a seal and control fluid flow. Main parts and materials Name/Material CI WCB CF8 CF3 CF8M CF3M Body CI WCB CF8 CF3 CF8M CF3M Diaphragm […]

Straight through type rubber lined diaphragm valve

A straight-through diaphragm valve controls fluid flow in a pipeline using a diaphragm that moves vertically to open or close the flow path. The straight-through design allows fluid to pass directly through the valve, reducing pressure drop and maintaining efficient flow. It is commonly used in applications where reliable sealing and minimal obstruction are needed, […]

Fluorine lined plug valve

A plug valve controls fluid flow in a pipeline using a cylindrical or tapered plug with a central hole. The plug rotates within the valve body to open or close the flow path. When the plug aligns with the pipeline, fluid passes through. When turned so the hole is perpendicular to the flow, it blocks […]

Fluorine lined control valve

A fluorine lined control valve regulates the flow of fluids in a pipeline, adjusting flow rate, pressure, and temperature. It works by changing the size of the flow passage using elements like plugs, balls, or diaphragms. Control valves are crucial in industrial processes for maintaining operating conditions and ensuring system efficiency. They can be operated […]
