"Y" STRAINER (for Shell & Tube Heat Exchangers And Air/Oil Coolers)
APPLICATIONS & SPECS. ("Y" Strainers) These strainers are engineered for water or steam, and are adapt- able for many other uses. Cleaning is accomplished by simply removing a pipe plug without disconnecting any piping. Or, if it is desirable to clean without interrupting service, a blow-off valve can be connected to the clean-out opening. Note: Pumps, control valves, traps, or other equipment controlling the flow of liquids or gases require proper protection with strainers for trouble free operation. 18 - Y BRASS STRAINERS The 18 - Y strainer body is a sturdy red brass casting. Standard units have 50 mesh brass wire screens. Brazing connections are available on special order instead of pipe threads. 20 - Y STRAINERS The 20 - Y strainer has a heavy cast iron body with accurately machined pipe thread inlet and outlet (National Pipe Thread N.P.T.). It contains a strainer screen of 0.02" thick brass with 100, 1/16" perforations per inch.
