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 moves gas from the input liquid pipe to the output gas pipe aiming to keep the pressure of the input at the target setting.

Purge Valve is an active powered device for controlled transfer of substances between the two pipe networks. Purge Valve will drain the gas from Input liquid pipe network and transfer it to the Output gas pipe network until a pressure limit defined by the valve setting is reached on Input network. Setting the pressure limit to 0 will pump the gases out completely, leaving only the liquids behind. When being placed, hologram indicators will display the Input liquid pipe arrow inward, the Output gas pipe arrow outward, and the power socket on its side. It has a pressure control valve, which defines the pressure limit.

Purge Valves are often used to collect a substance evaporated from its liquid state (such as Nitrous Oxide, often stored in its liquid form) before its practical use. Othar than that, it can be utilized to remove any undesired gas constituents from a liquid pipe. Used in conjunction with a Pressurant Valve, Purge Valve can be used to precisely control the pressure within a liquid pipe network for complex phase change operations.

NOTE: Since Purge Valve drains gas pressure from the liquid pipe and raises it in the gas pipe, this inevitably causes the liquids to begin evaporating. The evaporated liquid then may leak through the Purge Valve and inadvertedly condense into a liquid again, meeting the gas pressure it have just lost, which may cause the pipes to flood and burst. Make sure to backup the Purge Valve with a Condensation Valve going the opposite way to drain the liquid back into the liquid pipe, or maintain a safe pressure level and lower temperature in the liquid pipe to prevent that.
