The Dynamic Valve is a block added by Mekanism. It is used to build a Dynamic Tank multistructure to store fluids (shown in the picture). The Dynamic Valve acts as an interface between the tank and a connected fluid pipe system (e.g., Basic Mechanical Pipe). At least 1 valve is required and cannot be placed on the corners and edges of the multiblock structure.
