ABSTRACT:
A manifold box adapted to contain manifolds for valves controlling the flow of potentially hazardous liquids. This is a rotationally cast sealed plastic box enclosing the valves to contain any leaks from the valves and allow any leaking liquid to drain from the box through a drain tube at the bottom of the box to prevent the liquid from leaking onto surfaces below or adjacent to the valves. Attachment engaging "tee-nuts" are cast in place within the walls of the box and fittings for tubing connections are spin welded to the walls of the box. The box has a front access opening sealingly closed by a hinged plastic cover panel. In one embodiment the box is rectangular and is designed with two adjacent sloping walls which permit drainage of liquid from the box into a drain tube regardless of whether the box is mounted vertically or horizontally. In another embodiment the box is square and has one sloping wall containing a drain connected to a drain pipe.
