Product Description

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 sturdy construction and red brass material ensure long operating life and high reliability when used in combination with M6061/VMM and M7061/VRM actuators. The special inner form of the housing and the all-around changeable rotary plug allow the valve to be adapted to each possible application without having to drain the system. The DRR25 Three-Way Rotary Valve is especially designed for applications with sludge deposition and for panel heating (e.g. underfloor and ceiling heating systems) with oxygen diffusion. In combination with the distance-adjustable HE25 Extension, use in a wide range of prepiped systems is possible.
