Works well

Easy to install and set pressure. Has a built in dial for pressure setting and shut off valve on the bottom.

Yes

A colleague recommended this pressure reducing valve for radiant floor heating systems, and I've installed two already. Straightforward to set the pressure, takes out the guesswork of trying to remember which way to turn the adjustment screw and then checking the pressure repeatedly. Also service is very straightforward, based on my one chance to disassemble and clean an older one that I came across recently.

The unit can be installed in either horizontal or vertical position. It is, however, vital that the unit is not installed upside down. Please refer to page 3 of the Product Overview for installation instructions. https://s3.amazonaws.com/s3.supplyhouse.com/manuals/1346570329517/78374_PROD_FILE.pdf
