Gas Valve

Gas Valve is a pipe building that controls how much gas moves through connected Gas Pipes, preventing wasted gas and helping regulate pressure in a system. It does not create or destroy gas; instead, it caps the output flow so that only the configured amount can pass through, with any excess held back upstream.

Its flow setting ranges from 0 g/s to 1000 g/s, and the valve acts as an upper limit on output. If the incoming gas exceeds the limit, the valve restricts the flow to the chosen value. If the incoming flow is lower than the setting, the valve simply lets the available amount through. At the maximum setting of 1000 g/s, the valve no longer meaningfully restricts flow, since that matches the maximum throughput of Gas Pipes. Setting it to 0 g/s completely blocks gas from passing.

The flow value is adjustable in 0.1 g/s increments, meaning the value is rounded to one decimal place. Changing the setting requires Duplicant operation and takes some time, so it is not an instantaneous control method during rapid line balancing.

Gas Valve is most useful when:

• splitting a single gas source between multiple consumers,
• limiting supply to avoid backing up an overproducing line,
• feeding machines at a controlled rate,
• preventing a high-pressure line from overwhelming a branch.

Because the valve only limits flow, it is best used as a regulation tool rather than a storage solution. If the upstream pipe is already full and the valve is set too low, gas will remain blocked behind it until demand increases or the setting is raised. This makes it valuable for shaping distribution networks, especially where different machines need different intake rates or where a stable partial flow is preferable to full-speed delivery.

In practice, the Gas Valve is a simple but precise way to tune gas logistics. Its ability to fine-tune output in tenths of a gram per second makes it much more exact than on/off pipe control, and its maximum throughput matches the pipe limit, so it can be left fully open whenever restriction is unnecessary.
