Low maintenance, easy-to-install thermostatic mixing valves (TMVs) are designed to protect against accidental scalding, & increase amounts of available hot water.

The 3-way ESBE VTA Series thermostatic mixing valves replace Series 20 & 30MR styles of valves and are designed for point of source in domestic hot water distribution systems and/or regulation of supply in hydronic heating systems.

KOVM mixing valve bodies are designed to maintain room temperature by controlling hot (or chilled) water flow through radiators, fans, convectors, etc. Due to the KOVM’s unique bypass design, a constant system flow is achieved regardless of the room’s heating (or cooling) requirements. Therefore system pressures and flow rates are automatically kept constant without the need for pressure controlled bypass valves.

Lesson learned. The Intelliflow is a good idea, but it is built cheaply and does not provide any way to do your laundry if the unit breaks down. It was overkill.

The three way mixing valves feature anti-scalding technology and are available in a VTA Series Lead Free style or a VTA 570 mixing and diverting style for closed loop applications.

Last year I built a first floor laundry area and went hog wild with leak prevention. One component of my strategy was the Watts Intelliflow. It works by sensing when the washer is on and turning on/off the water. The idea here is to keep pressure out of the hoses when the machine is not being used. I have fantastic hoses (Floodchek - google them they are amazing), but the Intelliflow also has a leak detector sits on the floor below the valves.

The 3-way ESBE VTA570 can be utilized in a mixing or diverting application for hydronic closed looped systems (not for potable water). Typically, this thermostatic control is used as a non-electric alternative for a 2-pipe changeover diverting application.

Well, after one year the Intelliflow died. Since it uses the weirdest size connectors (to the plumbing, not the hoses) there was no way to just bypass it and get on with the laundry. My plumber is here right now and here is what we are doing. We are installing a new box and Burstbuster. The Burstbuster will not turn the water on/off as needed, but it has a leak detector AND if it ever fails (plumber says they never do), you can just take it off and hook up your hose(s) directly.
