This Rite-Temp pressure-balancing valve works behind the scenes to prevent scalding and thermal shock for optimal comfort. Additionally, the unit features a diaphragm design that virtually eliminates freeze-ups from contamination and water debris. When paired with compatible trim, this valve delivers a high-temperature limit stop and an optimal comfort zone, so you can set a maximum high and then find and maintain your desired water temperature.

  • Rite-temp pressure-balancing technology maintains water temperature within +/- 3°F
  • Provides anti-scald protection and temperature regulation.
  • Back-to-back installation is ideal for unique or high-volume jobs.
  • High-temperature safety stop ensures water temperature stays below 120°F
  • Mounting tabs located on rough-in for secure installation option.
  • 5.0 GPM (gallons per minute) flow rate.
  • Universal NPT and direct sweat connections need no additional parts for installation.
  • Requires valve trim (sold-separately).
  • Provides anti-scald protection and temperature regulation at flow rates as low as 1.75 GPM; far below federally mandated standards of 2.5 GPM

Rated 4.6 out of 5 by 22 reviewers.
Rated 3.0 out of 5.0 by Some good features The plastic trim ring has raised guides for 2x4 blocking which helps with the placement of the 2x4s, but there is movement of the valve in the trim ring and no means of directly attaching the valve to the blocking so extra care in securing the pipes is required. The position of the trim ring when attached to the blocking leaves just enough room for female adaptors to be screwed on to the valve outlet/inlets. The installation instructions are poorly written, are completely unclear in reference to several steps of installation and are severely lacking in explaining/picturing the attachment of the plastic ring to the blocking.

Rated 5.0 out of 5.0 by Kohler quality valve I like to buy things with the Kohler warranty and high quality. This part fit perfectly with the Kohler trim kit I had purchased. July 7, 2015
Rated 5.0 out of 5.0 by This is the way to go Hard to find this product on the shelves, shipped as advertised and price was the lowest around (including the manufacturer's direct buy price). June 15, 2015
Rated 4.0 out of 5.0 by Works great, easy to install Installed from open wall behind existing shower. Used PEX adapters, screwed and glued 2x4 mounting blocks. Instructions not too clear. Pressure fine, maybe a bit strong. November 20, 2013
Rated 5.0 out of 5.0 by Kohler Pressure Balancing Valve I purchased these valves for the renovation of the three bathrooms in the condo we just purchased. Home Depot could clearly deliver them in half the time of their competitors. I gave them to the plumber and he had no problems with the install. March 10, 2015
Rated 4.0 out of 5.0 by decent product well considering the first original unit didn't last as long as i hoped at least they make replacements still after a few years April 22, 2015
Rated 5.0 out of 5.0 by Works exactly as advertised, very satisfied with results We have been quite happy with the Rite-temp pressure balancing valve in our shower and after 3 years of hard water exposure, the scale build-up caused a leak. This valve was purchased mainly for its valve cartridge component. We initially tried contacting Kohler directly but the lead time for information (and quotes for parts we didn't want) took far too long. The quickest solution was to simply purchase a whole new valve and extract the components we needed. We have been very satisfied with the end results as our shower now works as well as it did when we first moved in. While my installation experience was excellent, I feel it would be unfair for me to rate it too highly since I was only replacing the cartridge and not the entire valve. The item was in stock, the price was acceptable, the shipping lead time was longer than I'd hoped but, in the end, the item arrived a few days early and in excellent condition. The time from online purchase to completed project was about 1.5 weeks. March 19, 2013
Rated 5.0 out of 5.0 by Cheaper than buying the individual parts Buying the whole assembly proved to be $20 cheaper that buying cap and valve assemblies indivudually at HD. In al liklihood, you will not need to swap out the brass piece in your home. Fixed the leak. March 19, 2013
