This valve has been salvaged from equipment (as evidenced by the cut tubing still attached to the ports).
This solenoid valve is an exact replacement for the 12 VDC normally CLOSED solenoid valve used in Keurig Coffee makers. I purchased one because it looked like the right one, and the seller’s description correctly listed it as normally closed. The incorrect description is from Amazon.
While I was disappointed that the solenoid was not new, I installed it and it works perfectly. My Keurig is now making full cups of coffee every time without my having to hit it or do any of the other things that have been recommended by users.
Solenoid valves are disassembled, the terminals are all over tin, but the function and performance are no different from the new solenoid valve.
