02.3 / VALVE & PRECISION SCREENS
Filter caps & small filter elements
Small mesh tubes, caps and screens with fittings provide inlet filtration in valves and precision equipment. Check fitting dimensions, sealing locations and effective filter area.
Start with a photo or drawing, even if some specifications are still unknown.

- Common materials
- SS304, SS316 / SS316L; confirm the alloy against the process medium.
- Construction options
- Mesh tubes, caps, edged parts or supported assemblies; construction follows the drawing.
- Dimensions
- Valve screen dimensions: outside diameter A, length L, fitting and sealing locations.
- Filtration requirements
- Mesh count, wire diameter or target filtration rating; confirm the rating definition and verification method.
Dimensions to discuss
Not to scale. Letters identify dimensions to be confirmed.
Valve screen dimensions: outside diameter A, length L, fitting and sealing locations.

- Valve screen dimensions: outside diameter A, length L, fitting and sealing locations.
- Key considerations
- A sample helps establish shape, but fitting dimensions, tolerances, medium and filtration needs still require checking. Matching appearance does not establish matching performance.
Filtration knowledge & FAQs
Is an old sample enough to specify a replacement?
A sample helps establish shape, but fitting dimensions, tolerances, medium and filtration needs still require checking. Matching appearance does not establish matching performance.
Is mesh count the same as filtration rating?
Mesh count describes openings per inch. Aperture also depends on wire diameter and weave; mesh count alone does not establish particle retention.
How do operating pressure and differential pressure differ?
Operating pressure is the system pressure. Differential pressure is the pressure difference across the element. Confirm operating pressure, clean pressure drop and maximum allowable differential pressure.
How are cleaning and maintenance determined?
Confirm cleaning methods, backwash conditions and replacement criteria against the equipment instructions and process medium, rather than appearance alone.
