OPTIMA Compact DN50-DN300

With OPTIMA Compact you get a dynamic flow and temperature control valve for heating and cooling systems

OPTIMA Compact combines the functions of an externally adjustable dynamic balancing valve, a differential pressure control valve and a full authority modulating control valve in one single, compact valve housing.

The OPTIMA Compact provides modulating control with full authority regardless of variations in the differential pressure of the system making it possible to achieve 100% control of the water flow in the building.

In addition, the correct application of the OPTIMA Compact can significantly reduce pump energy consumption and improve the efficiency of other hydronic system components. It also provides optimal comfort for end users due to high precision temperature control.

The valve operates by adjusting automatically to the pre-set flow under fluctuating pressure conditions whilst also providing full modulating control. To achieve the design flow rate, the simple pre-setting scale on top of the valve is rotated to the required set point, which can be determined by using the Frese flow tables or the Frese Valves app.
