[[Pressure Regulator]] is used throughout [[Atmospherics]] networks to manage [[Pressure]]. Pressure Regulators comes in two variants: Standard and back-pressure regulators. They can be used to separate two gas networks and as a one-way valve (in any variant, when set to zero).
  
 
The maximum pressure that can be set is 20265 kPa, which is double the maximum pressure for most gas-related elements like [[Canister]]s.

Pressure regulator needs power to operate (100 W). When unpowered it shuts off. That means it can be used as [[Pipe Digital Valve]]

==Description==
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:
+
The standard Pressure Regulator will pass through gases until the pressure on its output side reaches the set value.
* 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.)
 
  
To calculate the moles per tick, use the following equation:
+
=Back Pressure Regulator=
n = (P * V) / (R * T)
+
==Description==
 
+
The Back Pressure Regulator will only pass through gases once the pressure on its intake side exceeds the set value. (Not good as emergency dump very slow flow rate.)
Where:
 
* P = Min(Input pressure, 101.325)
 
* V = (OutputPipeVolume / InputPipeVolume) * 100
 
* n = Moles per tick
 
* R = Gas constant (8.3144)
 
* T = Input temperature

=Back Pressure Regulator=
 
==Description==
 
The Back Pressure Regulator variant will only pass through gases when the pressure on its intake side exceeds the set value. In other words, the standard Regulator defaults '''open''' and closes when the ''output'' is overpressured, while the Back Pressure Regulator defaults '''closed''' and opens when the ''input'' is overpressured.
 
 
Like the standard Regulator, the Back Pressure Regulator also acts as a check valve, switched valve, and compressor (i.e., input gas will move even if the output is already a higher pressure).
 
 
Its low flow rate makes it not suitable for being used as an emergency dump valve.
 
 
To calculate the moles per tick, use the following equation:
 
n = (P * V) / (R * T)
 
 
Where:
 
* P = Min(Input pressure, 101.325)
 
* V = 100
 
* n = Moles per tick
 
* R = Gas constant (8.3144)
 
* T = Input temperature

Back Pressure Regulator has exactly the same Network properties as the Pressure Regulator.

=Purge Valve=
 
==Description==
 
Allows for removal of pressurant gas and evaporated liquids from a liquid pipe. Similar in function to a Back Pressure Regulator, the Purge Valve move gas from the input liquid pipe to the output gas pipe, aiming to keep the pressure of the input at the target setting.
