2 and 3-Way Motorized Valves for the Steam, Vacuum, and Hydronic Heating Systems

Overview:

2-Way Valves for Steam Heating
Two-way valves can turn on or off the flow of steam from the boiler or other sources into a steam distribution system.  A typical example of this type of application would be using steam to heating radiators in a one or two pipe steam heated building using the MPC Platinum control.

2-Way Valves for Steam to Hot Water Heat-Exchanger
Two-way valves can be used to control the amount of steam entering a system.  A typical example of this type of application would be to regulate the amount of steam entering a heat exchanger to maintain the hot water output temperature using the HWR Platinum control.  When the load changes, the valve is signaled to change the amount of steam entering the heat exchanger.  See HWR Platinum control.

2-Way Valves for Vacuum Heating
Two-way valves can modulate the flow of sub-atmospheric steam from the boiler or other sources into a steam distribution system.  These actuators are equipped with a position feedback signal.  In addition, valve sizes up to 6” can be ordered with a valve percent opening gauge.  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 two-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 two-way valve reducing the flow of steam, or closes the valve.

3-Way Mixing Valve Applications
Three-way valves are used to mix heating water to a desired temperature. The hot water from the boiler is blended with the correct proportion of cooler water returning from the system to maintain the target temperature as the HWR Platinum control resets the hot water temperature based on outside temperature.
