SAUTER now has the solution to a problem that has been known for decades. At long last, automatically-controlled hydronic balance is possible, thanks to the pressure-independent SAUTER Valveco multi-function valve – a device that saves time, money and energy.

Hydronic balance in hot water heaters and water-based room cooling systems is a science in its own right. Estimates suggest that barely ten per cent of all heating plants and water-based air-conditioning systems operate under ideal hydronic conditions, which results in major distribution losses and a low level of energy efficiency.

Safe, reliable and constant

These problems are now a thing of the past. SAUTER Valveco regulating valves are genuine all-rounders, because they combine no less than three functions in one compact device: the Valveco acts as a balancing valve, a regulating valve and an internal differential-pressure controller.

Regardless of whether a flow merely has to be shut off or a set flow value needs to be kept constant, this unique valve safely and reliably counteracts the pressure fluctuations by acting as a variable resistance to ensure appropriate hydronic conditions in every plant. Limiting the flow greatly reduces distribution losses, and the pump design can be calculated more accurately than with conventional valves.

Plant extensions made easy

But this innovation from SAUTER offers even more benefits for consultants, installers and plant operators. With automatic hydronic balance, there is no need for manual fine-tuning – so much less time is needed to reach the commissioning stage. The flow limitation guarantees constant comfort for each individual user, while ensuring energy-efficient and cost-effective operation of the plant.

The flow can be set on the Valveco without dismantling the actuator. It can also be sealed, so, if any irregularities should arise in the plant, one glance is enough to determine whether the valve's settings have been changed. Another benefit is that the settings can be read as flow values on the scale on the setting wheel. This innovative multi-function valve also eliminates the need to use a graph. Last but not least, this three-in-one solution from SAUTER reduces both installation times and servicing costs.
