Common Questions

What pressure is it set to out of the box?

The adjustable reduced-pressure range of SS263RS-20-175 is 20 to 175 psi. Verify the outlet setting with a gauge after installation and adjust to your target pressure.

Does it include a strainer?

No - SS263RS-20-175 does not have an integral strainer. On dirty or older supply lines, install a separate inline strainer upstream to keep debris off the seat.

Does it come with a gauge?

SS263RS-20-175 has a gauge tapping (port) but no gauge is included - the port ships plugged. Thread in your own gauge to read the reduced downstream pressure.
