The ESBE thermostatic mixing valve of the VTA 570 series is designed especially for underfloor heating systems that require protection against scalding by hot water. This protection is necessary both for the pipes in the floor and at the same time for the floor itself.

This thermostatic valve is also suitable for pre-mixing in high-flow domestic hot water systems. In this case, additional, mandatory water temperature control devices must be placed on the water taps to ensure protection at the point of consumption.

The thermostatic valve can also be used for cooling applications.

Use

• Water distribution with antifreeze (≤ 50% glycol mixture)
• Closed water system
• Underfloor heating
• Cooling and cooling applications

Installation example

Valve function

The valve has an asymmetrical flow arrangement . It is also equipped with protection against scalding - if the cold water supply is interrupted, the valve automatically shuts off the hot water supply.

Properties

• Pressure class: PN 10
• Working pressure: 1.0 MPa (10 bar)
• Differential pressure: Mixing, max. 0.1 MPa (3 bar)
• The required temperature is set with the rotary knob under the upper plastic. cover
