Do not miss out

You’ve decided it’s time for a new master mixing valve. Great choice! But before you can enjoy the benefits of your investment, you need to make sure the installation is done properly. Follow these instructions:
Hot Water Recirculation must be continuous.

Hot Water Recirculation must be piped so the recirculation flow can reach the cold connection of the valve as well as the Heat Source.

Hot Water Rises. Therefore, a thermal loop is required in the Cold line at the connection to the heat source.

The recirculation temperature must be lower than the tempering valve set point.

High temperature recirculation, such as from a kitchen or laundry, must not reach the cold connection of a Master Mixing valve with a lower mixed temperature setpoint.

The valve must be installed to allow for access for service.

Perform routine maintenance.

Making sure your master mixing valve is installed properly is essential for ensuring efficient and accurate water temperature. By following the instructions above, you can be confident that your valve is installed correctly.

The Holby Tempering Valve is a top-of-the-line product that will last for many years. It’s not uncommon for our valves to be in service for more than 50 years, so learning how to properly install and service the valve is critical.

What Our Clients 
Say About Us

5 Stars rating

"I had some hesitation about placing a large order, but dealing with Holby completely changed that. For one, they actually answer the phone—every time. I spoke with Maria, who didn’t just take my order—she asked the right questions, helped troubleshoot a few concerns, and made sure I was getting exactly what I needed. It’s rare to find that kind of hands-on support these days. Holby really stands behind their product and their customers."

5 Stars rating

"It’s hard to believe there are only three internal parts in a Holby Valve—it makes servicing them incredibly straightforward. Once you’ve done it once, you realize how smartly they’re designed. And anytime I need parts, Maria gets them out the door the same day. That kind of responsiveness is a huge help when you’re trying to keep systems running without delays."

5 Stars rating

"I have been installing and servicing Holby Valves for over 30 years.  I wouldn't use any other mixing valve.  When something has been working for 95 years, you don't change it!"

5 Stars rating

"We had a job in New York City that hit a snag, and Holby didn’t miss a beat. They sent their field tech, Tim D., to meet me on-site. He walked me through servicing the valve right then and there, and we were back online in under an hour. That’s hands-down the best field support I’ve ever had—knowledgeable, efficient, and completely committed to solving the issue."
