Y Type Strainers

Y TYPE STRAINERS

Design features
  • These types of strainers are named after their shape and normally used for course filtration but with large filtration area can be used with fine mesh also .Body of Y strainer is normally of cast iron, cast carbon steel or stainless steel in various material grades with flanged end, threaded available with high filtration area and less pressure drop.

Features

Y Type Strainers feature bottom removal of the screen.

High Capacity flow through out full size In-let / Out-let connection with large Flow Filtration area to minimize Pressure Drop and screen chocking problems.

The cover is connected to the Body with Nuts & Studs and the filter screen is readily accessible and easily exchangeable.

The Y-Strainer are equipped with a blow off port.

A ball valve can be fitted to flush debris that is easily removable from the screen and exhaust to atmosphere or a drain system.

This feature allows for easy cleaning without interrupting the process. Various Perforations, Mesh or Perforation Mesh combinations or Wedge Wire screens are available to meet your process requirements.

Y type Strainer Strainers are used in application for Industrial use and are provided with most modern design and construction, in accordance with the latest requirement of National & International standards. These Strainers are recommended for most types of Industrial Applications, ideal for HVAC & R Systems, Petrochemicals, Textiles, Agriculture, etc
