Which pressure range is associated with a hot water valve in a controller setup?

The pressure range of 8-12 psig is typically associated with a hot water valve in a controller setup due to its operational requirements within heating systems. Hot water valves are often designed to operate effectively with a certain pressure to ensure proper flow and operation of the heating system. This pressure range facilitates the functioning of the valve under typical conditions encountered in commercial and residential applications, ensuring that it can open and close properly to control the delivery of hot water.

Additionally, this pressure range helps to maintain the integrity of the heating system by preventing issues such as excessive pressure that can lead to leaks or valve failure, and too low a pressure which can result in insufficient heating or flow. The specific range of 8-12 psig is considered optimal for many systems, balancing the need for good flow rates while remaining within safe operational limits.
