Abstract: A fluid valve support panel including a plurality of interlocking modules is disclosed. Each interlocking module is a rectangular planar member having a set of interlocking flanges and pockets disposed about the periphery of the panel. The pockets and flanges of adjacent panels interlock with one another to form a self-supporting set of panels. Opposite sides of the rectangular modules have inverse patterns of pockets and flanges which permit adjacent panels to be interlocked. A valve mounting plate having fluid ports formed therethrough is secured over a central aperture formed in each module. The valve mounting plate has a flat surface for receiving a valve on one side and is adapted to be secured to fluid piping means on the opposite side.
