Product Description
How energy efficiency is improved
Automatic dynamic hydronic balancing with the SAUTER Valveco compact regulating valve provides a correct supply to the downstream consumers and a reduction of temperature variations in the room, so that the use of energy is more accurate and more efficient
Features
- Regulating valve with three functions: Control, preset maximum volume flow, automatic flow regulation
- Range 30…11500 l/h
- Easy to preset the max. required volume flow
- Versions with and without pressure measurement nipple
- The valve is closed when the spindle is moved in
- Closing procedure against the pressure
- Slight adaptation of the proven SAUTER actuator technology
- Regulating valve with female (DN 10...DN 32) or male thread (DN 40 and DN 50) as per DIN EN ISO 228-1
- Flat-sealing regulating valve
- Differential pressure across the control unit is kept constant; valve authority 1
- Valve body and plug made of dezincification-resistant (DZR) brass
- Stainless-steel spindle
- Temperature range of medium 0…120 °C
