Would it be possible for a defective inductor commutator (resistor diode) paralleled with a solenoid coil could be not allowing the magnetic field within the coil to collapse quick enough, cause a FSV to have a slow to close stroke time?
The FSV operates as designed when energized, (Energize to OPEN)..but stroke to close time is approx 8 seconds..and spec's for this valve call for less than 4 seconds.
Also, this is the second, (brand new FSV that was installed)...it's sister valve is functioning as designed.
What wasn't changed was anything associated with the control and power circuitry of the FSV.
Would like to hear if there is any history or OE from the industry on this possible scenario thanks
