DEV STRAINER SERIES

FORGED
STRAINER

Strainers are filtration devices in fluid systems such as piping, pumps, and valves that remove contaminants such as sand, rust, and pipe debris. They protect downstream equipment, extend piping life, and support efficient operation—from industrial piping to everyday applications including domestic and light industrial installations.

STRAINER

Conforms to API 800/1500 and ASME Class 150-2500, with sizes from 3/8" to 2". End connections include socket weld, threaded, butt weld, and flanged. Key features include bolted or welded bonnets, outside screw and yoke design, solid wedge disc, and renewable seats. Materials include ASTM A105, A182-F304, A182-F304L, A182-F316, and A182-F316L for wide industrial applicability.
