strainer valve is a type of valve used to filter out unwanted solid particles from liquids or gases in pipelines. It protects downstream equipment such as pumps, valves, heat exchangers, and compressors.
Key Features:
1. Design:
Contains a mesh or perforated screen that traps debris.
Can be Y-type or basket-type:
Y-Strainer: Compact, ideal for inline installation.
Basket Strainer: Larger, suitable for high debris load.
Body materials: Cast iron (CI), carbon steel (CS), stainless steel (SS).
2. Operation:
Flow passes through the screen.
Solids are collected in the strainer basket or mesh.
Can be manual cleaning or blow-off connections for automatic cleaning.
3. Connection Types:
Flanged, threaded, or welded ends.
4. Pressure & Temperature:
Typically PN10–PN40, depending on material.
Temperature range depends on body and screen material.
5. Sizes:
Available in small to large diameters, from 1/2" to 1000 mm or more.
