Stainless Steel Pipeline Strainer Strainers are your most economical choice for large debris removal. They are most commonly used in pressurized lines, gas or liquid, but can also be used in suction or vacuum conditions. Y-Strainer has the advantage of being able to be installed in either a horizontal or vertical position. However, in both cases, the screening element or "leg" must be on the "downside" of the strainer body so that entrapped solids can be properly collected and held for disposal. The Y-Strainers 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.
