These ultra-high pressure valves are available in 1/16", 1/32", and 360 micron versions. There are three types - a two port on/off valve, a dual on/off valve, and a 3-way prime/purge valve. The dual on/off configuration has two individually controlled outlets with a common inlet (or vice versa), emulating a rotary three way valve.
Implementation requires a single three-way solenoid: application of 50 psi opens the valve; venting the air allows the spring to return the valve to the closed position. A fitting for 1/8" air supply tubing is included; two fittings are included for dual valves.
