Does anyone else have a problem with a loud buzzing coming from their ASCO valves? See video:

Thanks.
Two possibilities, you have placed an AC coil on a DC setup valve, or the piston that lifts is dirty and not making good contact with the stationary slug nut inside the stem. If it was a dc operated version then you are into a rebuild kit for AC which costs more than the Honeywell valve will, > $100 retail. If not then disassemble valve and clean the top surface of the piston and the inside of the stem, then it should be quiet again. Good luck and do not blow your self up with that setup.
