Style GA - Y Strainer (Cast Iron)

Natural Gas Service


Cast Iron

250# ANSI RF Flange

(ASTM A 126, Class B)

Steam, water, oil or gas where protection from foreign matter in a pipeline is required.

The 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.

The 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.

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.
