Metal sealed solution valve are ideal for quick response times and 24/7 usage, also there life expectancy is greatly increased, although dissadvantages are you need very clean air and a regulated temp range for optimum use. Even by leaving the valves over a weekend without use could enable the valves to “stick”, my opinion now would be to use a standard sealed valve, unless your requirements are for high speed and high usage.
