“Y” Strainer
Before installing the “Y” strainer, be sure its pressure
rating is correct for the system. If the end connections are
threaded or designed for soldering or brazing, be sure the
piping is straight and not at an angle or off set. If the strainer
has fl anged ends, be sure the fl anges of the connecting
piping are square with the pipe so that no undue stress are
put on the strainer or piping when tightening fl ange bolts.
Tighten in sequence, crossing to opposites.
For maximum effi ciency, a diff erential pressure gauge
installed across the inlet and outlet will indicate pressure
loss due to clogging and may be used as a guide to
determine when cleaning is required. Normally, when
diff erential pressure reaches 5 - 10 psi, screen must be
cleaned. If the strainer is equipped with a blow-down valve,
open and fl ush out until any sediment is removed. If the
strainer is not fi tted for blow-down cleaning, (strainer must
be off line), remove the cover or cap and clean the screen.
Reinstall the screen in the strainer in the same position
as before and tighten cover or cap. Replace the gasket if
necessary.
Keeping a spare, clean screen will minimize shut
down time.
Warning
Individuals performing removal and disassembly should be
provided with suitable protection from possibly hazardous
liquids.
Note: Large size “Y” strainers are supplied with
Breech-Lok screens. To remove screen, rotate screen 45
0 ,
Breech-Lok will disengage.
Spare Parts
To order replacement screens or gaskets, you should specify
the following:
• Size and model number of strainer or casting number as
it appears on the body of the strainer
• Specify the type of service. For example: water, steam,
gas, oil, air. The working pressure and temperature
of the system and the particle size to be strained out
should also be specifi ed.
