Product Description

The VRI/VRE Three-Way Rotary Mixing 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 brass material ensure long operating life and high reliability when used in combination with MRC actuator. The MRC actuator is designed to provide floating control in heating and air-conditioning systems. High control performance and rugged design are standard for that actuators. In combination with the VRI/VRE valves, it is possible to control very exact heating and cooling water temperatures. The mechanical interface between
