Description

"Pumps gas into a liquid pipe in order to raise the pressure" — Stationpedia

The Pressurant Valve is an active powered device for controlled transfer of substances between the two pipe networks. When active, Pressurant Valve will pump the gas from Input pipe network into the Output liquid pipe network until the 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.

Pressurant Valve is conventionally used for maintaining the liquid state of a contained substance (such as water), that would otherwise evaporate in absense of the background pressure. It can also be utilized to actively condense a cooled gas into a liquid by injecting a pressurant gas, or inversely to force the liquid to evaporate by injecting a heated gas and raising the temperature without the dedicated Pipe Heater (Liquid). The more efficient use of these principles require the knowledge of the gas phase change diagram, to pick an appropriate gas input, its temperature, and the target pressure, the combination of which achieves the desired final result.
