Digital Valves – Guide

The game has a digital version of the normal valve – but not of the condensation and expansion valve. This mod adds both as switchable valves plus six more valve types, each for gas and for liquid pipes. All of them work with a button, a logic switch or IC10, have their own model with coloured connections, a status LED and a data port.

Requirements#

• Stationeers 0.2.6428, BepInEx 5.4.23.5, StationeersLaunchPad 1.0, see Installation
• Mod in the active mod pack
• Multiplayer: server and all players with the same version

Quick start#

1. In the Hydraulic Pipe Bender (tier 1) make a Kit (Digital Valves Gas) or (… Liquid): copper 2, steel 5, invar 3.
2. Take the kit, pick the valve with the mouse wheel, rotate with C + mouse wheel and place it into the pipe.
3. The inlet is the stub whose arrow points at the housing. Yellow ring = gas, blue ring = liquid.
4. Cable (power + data) at the socket with the red-green ring – on the inline valves on the side opposite the panel, on the diverter, distribution and merging valve on top. Every valve needs 5 W.
5. Press ON/OFF on the panel. The LED turns yellow (ready) or green (open).

The valves#

All except condensation and expansion come in a gas and a liquid version.

Digital condensation and expansion valve#

The same code as the game valve runs here: per tick (0.5 s) at most 10 litres pass, at most half of the liquid at the inlet, and only as much as fits into the outlet line. The gas stays where it is. The mod only switches this tick off while the valve is off or unpowered.

That is the key to same-tank distillation: several condensation valves sit on the same tank, each on its own liquid line. Condensate only ends up where the valve is switched on.

3-way diverter valve#

The PATH button toggles between A and B, LEDs A and B show the open path. When open it behaves like the game's Digital Valve: both networks equalise by volume within one tick, in both directions. Closed without power.

Throttle valve#

The opening (Setting 0–100 %) is the share of the equalisation per tick: 100 % = like the Digital Valve, 50 % = half the way per tick, 0 % = closed. Buttons - and + change by 10 %, holding C by 1 %.

Thermostatic valve#

The sensor sits at the inlet. Mode "opens above": open once the inlet is warmer than set point + ½ hysteresis, closed below set point − ½ hysteresis. Mode "opens below" the other way round. Hysteresis 1 K (IC10 put address 2). Buttons: -/+ 5 K (holding C 1 K), MODE. The valve works mechanically without power too; LED and data need power (can be switched off in the settings).

Safety relief valve#

When the inlet pressure rises above the set pressure (Setting, preset gas 45,000 kPa, liquid 4,500 kPa) it opens and relieves into the network at the outlet until the pressure is the reseat margin (5 %) below. It never pushes against a higher back pressure. In a brim-full liquid line it drains liquid first (at most 10 L per tick). Every trip is counted; the alarm stays latched until RESET is pressed (holding C also clears the counter) or IC10 writes Activate 0. LED: flashing red while relieving, flashing orange while an alarm is latched. Works mechanically without power.

Distribution and merging valve#

Each branch has a button A, B, C with an LED: click = open/close, holding C cycles the opening 25 → 50 → 75 → 100 %. Flow goes one way only, like the game's one-way valve: gas when the pressure on the feed side is higher, liquid when the fill level there is higher – never back. Branches are served in turn so none is preferred.

Status LED#

The lamp on top of the housing shows the same as the status LED and can be seen from every direction.

Sounds#

The valves use sounds from the game, positioned at the device and at your volume setting – every player hears the same: a clack when opening and closing (like the Digital Valve), a click on every button, the "pressure high" announcement when the safety relief valve trips followed by a warning beep every 5 s until RESET, and a hiss while it relieves.

IC10#

All valves sit on the data network with their names – best use lbn/sbn with the labeller name.

Memory (get/put):

On the distribution valve Output = A and Output2 = B, on the merging valve Input = A and Input2 = B; branch C only via get.

Same-tank distillation#

The game condenses a gas by the total pressure of the line: if the pressure is above the gas' minimum pressure and the temperature below its condensation temperature, all of it turns liquid – no matter how much of it is in the mix. Condensation temperatures (from the game data, Mole/MoleHelper):

So water always condenses first. Pollutant only condenses before CO2 from about 2930 kPa – below that it is the other way round. Since the pressure drops while cooling and with every substance taken out, a carrier gas that does not condense helps (nitrogen, condenses only below about 173 K at 4000 kPa).

Setup:

1. A tank (e.g. large tank) as the gas network. On it three Digital Condensation Valves, each with its own liquid line and tank. Labeller names: Destille Wasser, Destille Schadstoff, Destille CO2.
2. An Air Conditioner in a loop with the tank (inlet at the tank, outlet back through a one-way valve, waste heat outside). Name Destille Kuehler.
3. A small LED display Destille Stufe (shows the stage).
4. All devices and an IC housing with the script below on the same data network.

How it runs: stage 1 keeps the gas 3 K above the condensation of pollutant and CO2 (at least 1 °C) – only water turns liquid, only the water valve is open. Stage 2 cools to 3 K above CO2 condensation: pollutant. Stage 3 cools to 3 K below CO2 condensation (never below −54 °C, CO2 would freeze): CO2. A stage is done when less than 0.1 % of the substance is left. Stage 4 = done, all valves closed, air conditioner off – when new gas arrives in the tank the script starts again. A valve only opens once nothing else is liquid (otherwise the script keeps the tank warm until it has evaporated again). The display shows −2 or −3 when the pressure is too low for that stage.

In the simulation (8 MPa, 10 % steam, 15 % pollutant, 35 % CO2, 40 % nitrogen) every substance ends up more than 99 % pure in its line.

What you can tune: ABST (distance to the condensation temperature, 3 K), REST (when a stage is done, 0.001 = 0.1 %), NEU (share of new gas that triggers a restart), the device names. If a valve is missing (wrong name, not on the data network) the script closes all valves, switches the air conditioner off and shows 0.

Console#

Settings#

In the LaunchPad window or BepInEx\config\dominik1199.digitaleventile.cfg (in multiplayer the server's values apply):

Multiplayer and saves#

The server and all players need the mod in the same version. Settings, branch openings, counters and alarm are saved. The game's valves stay unchanged. Without the mod its valves disappear from the save.

Troubleshooting#
