#42 Get In the Zone! (with Mike Schreiner)

July 18, 2023 • Caleffi North America, Inc. • Episode 42

In this episode, Greg and Dan talk to "the man, the myth, the legend" of zone valves, Mike Schreiner, Caleffi CTO. Mike has been working with zone valves for his entire career and is pleased to share his wealth of knowledge to help our Ask Caleffi audience learn:

What's important when considering a zone valve? How do you properly size? What is the flow coefficient (a.k.a. Cv or differential pressure) and why is it important? BTW: there is a BIG difference between close-off pressure and system pressure! Zone valves and actuators... say what? In which application is a 2-way valve best used? A 3-way? How are end switches applied? What's the difference between a micro-switch and a Reed switch? Normally Opened. Normally closed. Why Z-one? (one valve for ALL!) Valve versatility with union connections. How about relay boards? (you CAN'T wire a zone valve wrong with a relay board!)

All this and MORE when you Get in the Zone with Mike!
