%% Shapes are always 2x their defined size value, I.e. a \TikZValveSize = 0.5 leads to a total valve height of 1
%% The default setting for elements is to have a span of ``1'' across the connecting sides.
%% elements can be rotated using the ``rotate around={angle:(point)}'' keyword, use in 90 degree steps is advised
%% While the rotate option may be inconvenient, it avoids the clutter of requiring multiples of every shape
