Description
The Johnson Controls P70DA-400 is an SPST manual reset open-high pressure control that makes sure that the HVAC is safe. It offers reliable performance with a pressure range of 200/610 PSI and measures changes in the pressure in the system through its 1/4″ pressure connection and 36″ capillary length. If the pressure rises above the set values, the control stops the circuit to avoid equipment breakdown or failure. Used widely in commercial and industrial air conditioning systems, it guards compressors, pumps, and other critical machinery from pressure fluctuations that may place them beyond a limit. Its manual reset function requires action after it has tripped, making system operators of any pressure that may affect functionality or productivity.
