Ive got a couple fisher scientific dual stage regulators with clippard mme-2QDS 110V solenoids, needle valve, and fittings. The needle valves are just basic needle valves I had and will work, but are not capable of super fine control as a more advanced metering valve. The solenoids are brand new and already wired up. These were built for people locally but fell through. One of the high pressure gauges was replaced on one of the regulators. Low pressure gauges are 0-60 psi. Both have been tested. Also have 2 extra brand new solenoids that I can wire up. Asking $160 shipped per regulator and $28 shipped per solenoid. PM me with questions
