What is the general thought of using 120V solenoid valves while maintaining NFPA 70E guidelines? I would think that as long as the connections and cables are hermetically sealed and the wires run to a box designated for >50 voltage, there should be no problem.
There are some opinions about mixing voltages, but sometimes, logistics, supply availability, and existing designs mandate the use of 120V solenoids. Therefore, using <50 for the entire control system except for the valves should be acceptable. There are 6mm "slim" relays that make it easy to design a compact interface box that handles the >50 devices and distribution.
