These are three used Numatics valves that have been resealed. There is one 554SA43AK000030 valve that is solenoid operated with a 110-120 volt coil. It is a two position valve with 1/2" npt ports, and a max operating pressure of 150 psi. The other two valves are a 11BAA4410A00000 that have a push button shift. They have 1/8" npt ports and a 150 psi max operating pressure. If you have any questions I'll be glad to answer them as best I can.
