Direct Mount Operator- B26000
The EVO is a self-acting, adjustable, non-electric
thermostatic operator. It has adjustable max./min. temperature, selected temperature locking feature and can be shutoff completely if required.
The symbol * protects against frost damage. Each EVO thermostatic operator is individually calibrated and conforms to ASHRAE standardization rules for temperature regulation. The EVO’s smooth shape and narrow air gaps gives a nice operation and makes it easy to keep clean. They can be mounted on all Macon NT series valves. Millions are in use throughout the world.

The Macon one-pipe steam valve assembly (OPSK) consists of the reliable MTW direct mounting thermostat. The thermostatic head contains a temperature sensitive wax which expands and contracts on a rise and fall of temperature in the sensed area. When the temperature rises above the temperature selected, pressure from the expanding wax closes the valve, preventing or restricting the flow of steam through the radiation unit. When the room temperature drops below the selected temperature, the valve opens and allows an increase of steam flow through the radiation unit. This modulating process continues automatically to maintain the temperature you selected....
