By the way the solenoid sold for the Moroso accumulators is a generic valve - nothing special about it other than the price.

Moroso electric valve $229: https://www.moroso.com/solenoid-valve23905/

Generic valve $40: https://ussolid.com/u-s-solid-3-4-b...lly-closed-viton-air-water-oil-fuel.html

available in stainless for $50: https://www.amazon.com/Stainless-Steel-Electric-Solenoid-Valve/dp/B00DQ24GS6

just need to search for the correct port size (I linked 3/4 but Moroso is 1/2 NPT)
