Heat-Timer 928074-00 4″ Double Seated 2 Way Motorized Valve Vacuum Steam Heating Service

Description

Vacuum Steam Heating. 2-way valves can modulate the flow of sub-atmospheric steam from the boiler or other source into a steam distribution system. Actuators are equipped with a position feedback signal. A typical example of this type of application would be using vacuum steam to heat radiators in a building. When the control, such as the SRC Platinum, calls to put heat into the system, the 2-way valve partially modulates open and steam flows into the radiators based on the outdoor air temperature. Then when the control determines that sufficient heat has entered the radiators, the control marginally closes the 2-way valve reducing the flow of steam.
