Strainer valve can be defined as a pipe fitting through which liquid is passed for purification, filtering or separation from solid matter; anything used to strain a liquid; any device functioning as a sieve or filter used to prevent solid bodies from mixing in a liquid stream or flow line. Strainers arrest pipeline debris such as scale, rust, jointing compound and weld metal in pipelines, protecting equipment and processes from their harmful effects, thus reducing downtime and maintenance.

WHERE ARE STRAINERS USED?

Often, industrial strainers are upstream of valves, compressors, and pumps. These are sensitive equipment that makes the pipe system more dynamic and efficient. Additionally, industrial strainers are effective when the media is heavier or contains contaminants which need filtering.

• Food Industry

•  Water Treatment Industry

• Petroleum Industry

Strainers: Why Choose Them?

• In liquid systems, the pocket should point vertically downwards. This ensures that the removed debris is not drawn back into the upstream pipework during low flow conditions.

• Although it is recommended to install strainers in horizontal lines, this is not always possible, and they can be installed in vertical pipelines if the flow is downwards, in which case the debris is naturally directed into the pocket.

Types of Strainers

• Y type Strainers

• Basket type Strainers

• T type Strainers
