OptionsTypical InstallationX Ref Features Applications
Many water pressure reduction applications involve water that has a high concentration of sand. Sandy
water results in frequent integral strainer cleaning. The model 600 is just the regulator for these applica-
tions. The model 600 has its strainer accessible through a separate cap. Unlike other regulator designs
that require disassembly of the valve, the model 600’s screen is accessed by the removal of a single cap.
This will drastically reduce the time needed to clean the strainer screen. Just like the 500 series, the 600
is also equipped with a union inlet connection and a female NPT outlet connection.
Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance with the latest edition of
the Uniform Plumbing Code. The Model 600 may be installed in any position. If installed in a pit, vault or indoors, specify the “SC” sealed cage option.
Multiple installations are recommend for wide demand variations or where the desired pressure reduction is more than 4 to 1 (i.e.: 200 psi inlet reduced
to 50 psi outlet). CAUTION: Anytime a reducing valve is adjusted, a pressure gauge (Model HGI-25) must be used downstream to verify correct pressure
setting. Do not bottom out adjustment bolt on bell housing.
