Cast Iron Y-Strainer
APPLICATIONS
Steam, water, oil or gas where protection from foreign matter in a pipeline is required.
CONSTRUCTION
The Keckley Style A strainers are constructed from rugged cast iron castings that are machined to exacting specifications. These bodies have drilled flanges that are in accordance with ASME B16.1.

The Keckley Style GA strainers are used extensively for protecting gas meters and compressors in metering stations. The strainer utilizes a Buna N-70-Durometer O-Ring instead of a conventional gasket on the solid cover plate.
FEATURES
The Keckley Style A strainer features a machined groove in both the body and cover for proper screen alignment and to ensure accurate reseating when servicing is required. The gasket is a synthetic fiber that is compressed between the body and cover for maximum strength and durability. Keckley Style A strainers can be furnished with a blow-off plug upon request.
SCREENS (View Screen Options)
Standard perforated 304 stainless steel screens are spot welded along the seam for maximum strength. Different size perforations and meshes are available in stainless steel, monel, and brass to meet specific media requirements. If the media is not indicated, screens for water will be supplied.
SELF CLEANING
Self cleaning is accomplished by opening the valve or drain plug connected to the blow-off port. Warning: See Maintenance Instructions on page S6 of the Strainer Information Section for additional precautions and detailed information on servicing the strainer.
