Pilot operated valve question

[Pescadortio]

Hello,

I am new to the forums and am currently working on a new build and have run into a dilemma. I will be using co2 as the propellant that will be used with the 3-way directional valve to chamber to barrel setup. I doubt I will have the need for more pressure, however it appears to me that most of the 3-way DCVs I've seen online max out at 115psi. However, the pilot operated valves can operate at a much higher pressure so that is what I'm leaning towards, with the setup having a small solenoid valve actuate the larger DCV for greater flow and pressure. My problem currently is that the pilot operated DCVs require a pilot pressure of anywhere from 20-40psi. should I simply tap into the line with a T connector and have a regulator bring down the pressure to 20psi and then have that lined to the pilot operated DCV which has the inlet hose sourcing from the original T I mentioned or is there a much simpler way of making this happen?

Have you considered using a slide-check valve as used on paintball remote lines?



They can take full CO2 pressure without issues, and with enough flow to pilot a QEV adequately.
