Niezgodka Type 81 Sustaining Valve

Introducing the Resideo DRG Three-Way Mixing Valve (Centra DRG), your ideal solution for precise water temperature control in heating and air conditioning systems.

This mixing valve is expertly engineered for optimal mixing control of supply water temperature in both heating and air conditioning applications. Constructed with durability in mind, it guarantees a long-lasting and dependable operation when paired with VMM and VRM actuators.

The Centra DRG rotary valves are specifically designed to ensure that both inlets flow through the valve at an angle, providing flexibility as the supply and return flows can easily be interchanged.
