Controlling the flow of gas between two pipe networks, pressure regulators shift gas until a set pressure on the outlet side is achieved, or the gas supply is exhausted. The back pressure regulator, by contrast, will only operate when pressure on the intake side exceeds the set value. With a max pressure of over 20,000kPa, it requires power to operate.
- Stationpedia

The standard Pressure Regulator will pass through gases, in one direction, while the pressure on its output side is below the set value. It combines several functions:

  • Passive check valve: Gas is never allowed to pass "the wrong way", from output to input, even if the Regulator is switched off or unpowered. (It does not allow gas to pass at all when switched off or unpowered)
  • Switched valve: Gas will not pass at all if the Regulator is switched off or unpowered. This is a similar function to the Pipe Digital Valve.
  • Regulator: Gas will only pass when the pressure at the output is below the Regulator's setting.
  • Compressor: While active, the Regulator will move all available gas from input to output, up to the set pressure. (Contrast with, for example, a Pipe Valve which simply equalizes pressure and then stops.)

The maximum pressure that can be set is 60795 kPa.

To calculate the moles per tick, use the following equation: n = (P * V) / (R * T)


  • P = Min(Input pressure, 101.325)
  • V = (OutputPipeVolume / InputPipeVolume) * 100
  • n = Moles per tick
  • R = Gas constant (8.3144)
  • T = Input temperature
