where to get new solenoid for an air valve?

pic of my valves

I have a valve where the blade connector broke off and is irrepairable. Does anyone know where I could just get a new solenoid? I bought my valves on Ebay from M&M or A-Z motorsports?? something like that....Anyway I can't find that company now. I think the valves are herion or blitzluft? Do you know from looking at them?
