Default Solenoid valve seems to be stuck open above 60psi?

Hello - long time no see, everyone!
Since I last posted here, I have sold the Camry and the 46115 horns, and have since bought a 2020 Kia Soul GT-Line Turbo and a Strombos Duplex horn.
I absolutely love the sound so far (basically a budget Kahlenberg D-2!), but I'm only able to sound them off at about 50psi, because if I fill the tank above 60psi, the horns start to honk themselves! Everything works normally below 60psi. I can honk the horn and it'll sound off, and stop sounding off when I let go of the button I use to activate it.



I'm using this valve


Here's a video of it happening while I was in the middle of installing everything. Anyone know what might be causing this? Do I just need to get a new valve?

Yeah, sounds like the solenoid for the valve or the valve itself has failed.

Replace it with one made for a higher pressure and see what happens.

Just called HB. Could be a faulty electrical switch or I could have been stupid and installed it backwards. I'll check those out later today.

Yeah, the "backwards install" will likely be the culprit. Check that first. Should be an arrow on it showing flow direction.

either your valve is on backwards or there is a tear in the Rubber Seal that seals the output. Give HB A Call if thats the case.
