Optimizing Mixing Valves in DHW Systems

Mixing valves are used every day in domestic hot water (DHW) systems. Whether you’re designing a system with a mixing valve or servicing an existing installation, there are a number of considerations in order to ensure accurate control of the water temperature. Don’t let the mixing valve be your go-to fall guy when expectations aren’t met! Cody Mack will come alongside our audience to help them design, install AND maintain a trouble-free DHW application.

You'll learn:
→ What is recirculation creep and how is it prevented?
→ Why is there a maximum pressure differential between hot and cold on a mix valve?
→ Sizing is based on high-flow, but what about low-flow considerations?
→ What is the impact of water quality on a valve?
→ I want 120°F from my mixing valve. What should I set my source to?
→ What is Cv? How is it applied?
