## Description

> *"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 is an active powered device for controlled transfer of substances between the two pipe networks. Pressure Regulator will use the gas from Input pipe network to pressurize the Output pipe network until a target pressure defined by the valve setting is reached or exceeded, or unless the input pipe runs dry. When being placed, hologram indicators will display the Input pipe arrow inward, the Output pipe arrow outward, and the power socket on its side. It has a pressure control valve, which defines the target pressure.

The most common use for a standard Pressure Regulator is to place one ahead of a [Gas Tank Storage](/wiki/gas-tank-storage) unit to safely fill the inserted [Gas Canister](/wiki/gas-canister) or [Gas Canister (Smart)](/wiki/gas-canister-smart) with gas input without overpressurizing it. Similar principle can be used to maintain the desired pressure level in any pipe network or room.

The maximum pressure setting is 60795 kPa - a critical pressure limit for a pipe network before it begin to take damage.

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

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