Short Description
A strainer valve is a mechanical device installed in pipelines to remove debris, dirt, rust, or other solid particles from the fluid (liquid or gas).
It protects pumps, compressors, meters, control valves, and other process equipment from damage caused by impurities. Strainers are typically used at the inlet of equipment and require periodic cleaning of the screen/mesh.
Key Features
- Filters out unwanted particles to protect downstream equipment
- Available in Y-Strainer, Basket Strainer, and T-Strainer designs
- Removable mesh screen for easy cleaning and maintenance
- Suitable for liquid, gas, or steam applications
- Reduces the risk of clogging in pumps and valves
- Available in wide range of sizes and pressure ratings
- Cost-effective solution for pipeline protection
