O2 safety valve

[Weschap]

I'm curious what solenoid operated valve others are using for stick blending nitrox. My system is 12 volt and I can easily wire into the control circuit to operate the solenoid.

I know you might want something a little ready to go, but you can save some money by putting it together yourself. I bought 4 Peter/Paul Valves on Ebay for about $35.00. These had 5000psi NC valve bodies and 125v coils. 1 for each stage for auto drain and 1 for Oxygen shutoff. Find a NC valve body rated for at least 100psi and the voltage used for the pressure cutoff. Install it AFTER your metering device. Wire the coil across the NO contacts on the pressure switch so that if the compressor shuts down, the valve closes. Put a jumper to power the valve form the control line to the compressor.
