DTW Direct Mount Operator

Overview

The Macon DTW thermostatic valve will help you balance your heating system. The DTW operator has one of the most accurate sensors available for radiator temperature control. The problems of overheating, underheating and wide temperature swings can now be minimized.

The DTW thermostatic valve by Macon Controls conserves energy by regulating temperature. Fuel costs can be reduced up to 30%!

The DTW is a self-acting adjustable non-electric thermostatic operator. It has an anti-freeze position, adjustable max./min. temperature settings, selected temperature locking feature and can be shutoff completely if desired. Each DTW thermostatic operator is individually calibrated and conforms to ASHRAE standardization rules for temperature regulation. The DTW ’s smooth shape with narrow air gaps is a very functional design and allows for easy cleaning. DTW has a connection that is M30x1.5 and will be delivered with an adapter for MMA’s valves so they can be mounted on all Macon NT series valves.
