Product Description

The DRU 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. In combination with the distance-adjustable H-Extension, use in a wide range of pre-piped systems is possible.
