Description
The Johnson Controls P47EA-1 Steam Pressure Control, is a durable control in the process of controlling the pressure of steam for HVAC systems. This control device has pressure range of 50 to 240 PSI which makes it suitable for use in most of the steam applications. It has a high performance SPDT output that makes it possible for it to toggle between the two circuits. This I believe helps in raising the capacity of the steam system; it also helps in ensuring that the pressure of the steam system is well regulated through maintenance. The ability to cover a wide range of pressure demands is a strength, as is the reliable SPDT output for controlling the steam pressure.
