FIG. 7260
Tee Strainer
The Fig. 7260 Tee Strainer provides an economical, compact
and hydraulically effcient means of protecting valuable piping
system components. The in-line, twin-fold strainer basket
provides more than 100% of the projected pipe area for open
fow through the strainer screen which results in excellent
fow performance across the strainer.
Gruvlok Strainers are designed and tested to ensure long term,
reliable service in working pressures up to 750 psi (51.7 bar),
depending on size and the pressure rating of the connecting
coupling.

NOTE:
Most U.S. piping engineers specify system startup instructions for new systems which include remov-
ing and cleaning the strainer screen after system fushing of main piping before the system is put
into normal operation. After fushing, replace the strainer screen. Flow data values are based on
fow of clean water at ambient temperatures. The pressure drop across a strainer, 50% clogged,
is approximately twice as great as that of a clean strainer. Strainer baskets need a routine
maintenance program to maintain effciency and to prevent excess pressure drop caused by a
clogged screen.
