A pressure regulator is a type of control valve used to release a highly pressurized fluid at a set lower pressure. This allows for a variety of liquids and gases to be safely and efficiently manipulated for a number of different purposes. As such, this valve is a necessary component of many devices and machines found in Polycraft. The second tier of regulator available for crafting in Polycraft can handle greater pressures, offering access to stronger versions of existing devices as well as entirely new devices and machines. Like the low pressure variant of the pressure regulator, this item is a component of multiple machines needed to progress through Polycraft's tech tree, namely the Chemical Processor and the Merox Treatment Unit. To craft this item, you will need redstone and multiple of both Gasket (Medium Pressure) and Hose (Medium Pressure) as specified in a recipe below. However, it should be noted that one will need access to an Injection Molder and an Extruder in order to craft any gasket or hose, respectively. Also, since these are medium pressure items, stronger plastics will be necessary to create them. The plastics available in the crafting of these items include Bag (PolyButadiene (high-cis) Pellets), Bag (Isobutylene Rubber Pellets), and Bag (PolyButadiene (low-cis) Pellets), however, the first plastic listed requires one has already crafted a Chemical Processor. The other two plastics are attainable if one has access to a Steam Cracker through a variety of different recipes. One final note, the machines needed for the crafting of a pressure regulator both need fuel and water as well as the proper molds to specify what you are crafting. Both the Mold (Gasket) and Metal Die (Hose) will need to be crafted using a Machining Mill.
