Pressure Valve

Group,

I have a burn table from the early 70's and need to replace the 3 vavles. The specs are as follows. I can show pictures if needed of the valves.

volt/hz 120/60

psi 100

watts 10

orifice 5/32

valve # v5d47830

The have skinner electronics name on them. Can someone tell me a replacement part or maybe where I can get the same valve?
