CONSTRUCTION
Extremely rugged bodies in cast carbon steel (ASTM A216 Grade WCB). These strainers
are well designed for medium or coarse straining. The angular cutaway design of the
baskets allows a straight through fl ow and results in extremely low pressure loss. All
sizes feature the fl anged top cover connection and easy basket removal. Bodies can be
supplied with tappings for pressure gauges. Tapped and plugged NPT drain connection
sizes shown on next page. See chart on page D-3 for pressure drop fi gures.

blowoff outlet to fl ush off accumulated sediment.
