The ESBE VTA 320 series thermostatic mixing valve is a suitable component for universal use in domestic hot water installations equipped with HWC (hot water circulation). It is also suitable for smaller underfloor heating circuits (up to 50m²) when special attention needs to be paid to temperature range and flow rate.

A non-return valve for cold water inlet is included.

Applications

• Distribution of fresh/drinking water
• Water distribution with antifreeze additive (≤ 50% glycol mixture)
• Closed water system

Installation Example

Valve Function

The thermostatic valve has an asymmetrical flow arrangement. The desired temperature setting is adjusted using the rotary knob under the valve's top cover. It also includes a very important anti-scalding function, which automatically shuts off the hot water supply in the event of a cold water supply interruption.

• Operating pressure: 1.0 MPa (10 bar)
• Differential pressure: Mixing, max. 0.3 MPa (3 bar)
