[. . . ] THREE-WAY ROTARY VALVE PN10 AND HE25 EXTENSION PRODUCT DATA DRR/HE FEATURES · Chrome-plated plug for long life-span · Optimized characteristics for supply water temperature control · All around changeable rotary plug · Reliable and easy mounting of electrical actuators · Wide range of flow rates in two housing sizes · Compact design · Use for manifolds by accessory HE25 Extension · Thermal insulation package included APPLICATION The DRR25 Three-Way Rotary Valve provides water temperature control in heating and air-conditioning applications. These valves are designed for accurate mixing control of supply water temperature and return-flow temperature. [. . . ] The required flow water temperature is achieved by adding a proportion of return water to the boiler hot water. The DRR has special control characteristics for optimal control performance.

The rotary valve can be set quite easily. In order to obtain good control characteristics, the pressure drop in the rotary valve should be about the same as the pressure drop in the "volume-variable" part of the pipe system, i. e. The following dimensioning diagram is based on this interrelationship. 4. & Find heat flow Q in the diagram. & Move vertically upwards to the intersection with the corresponding line. On the vertical axis, the volume flow V can be read off on the left in liters per hour. Move horizontally to the right from the intersection with the line into the shaded section (1. 5-4. 0 kPa).
