Pressure-Controlled Fluid Flow Valve

[SupplyDepoo]

Add a small fluid valve with four fluid connections, which controls fluid flow by pressure difference.

Details:

• Two fluid connections (A and B) on opposite sides allowing fluid to flow from either side to the other, at a rate that is proportional to the valve aperture.
• Two valve controls:
  • One fluid connection (+) which applies pressure to open the valve.
  • One fluid connection (-) which applies pressure to close the valve.
• The valve is closed by default.

Pressure = fluid box fill percentage. (I think this makes sense at least for gasses like steam.)

Examples:

• When no fluid/pressure is applied to the two controls, the valve is fully closed.
• When pressure is applied only to the first control, the valve is opened by the same amount.
• When pressure is applied only to the second control, the valve remains fully closed.
• When pressure is applied to both controls, the valve opens proportional to the pressure on the first control minus the pressure on the second control.

This new valve type could be used to perform analog computations without electricity or circuitry and may have other applications.
