solenoid valve buzz
(OP)
Hi Guys, I'm still kinda stuck on my solenoid buzzing problem. The application is a pressure vessel that uses a solenoid valve to activate the discharge of water. The valve system is balanced by the pressure in the system, and the solenoid overcomes a spring force lifting a valve off a seat, discharging the fluid. The valves seem to buzz loudly when discharging water. I beleive this could be a coil problem...?? The fluid is still discharged, but the noise is not evident when no water is in the system. How can i check to see if the coil is working correctly.. It is 110V 50-60hz. It seems i need more force to lift the armature.





RE: solenoid valve buzz
Measure the voltage across the coil, as close to the coil as you can.
Compare with the rated values.
I'm guessing one or both will be low.

Is this a used valve with a lot of service?
