Zone detection faults on diffrent solenoids

Hello! I have the an issue with zone detection faults on diffrent solenoids, very sporadic, it will work 50% of the time. I checked the voltage at the valve terminals when working is 27volts, the rating of the valve is 24volts AC, 5watts at 0.2 amps the valve is working systematically with a dedicated 24Volt AC supply. When it is wired to the Rachio3,diffrent valves fail at random times. I have three zones conected with the same type valve, no master valve or rainsensor conected.
Can anyone help ?
