Williams WM498-108 Multiple Valve Manifold Panel Assembly

The WM498 series comprise a variety of push button, rocker, toggle, and knob-actuated valves. With end caps, spacing blocks, and supply manifolds, the WM498 series valves are grouped together in multiple valve manifold panel assemblies. Each manifold assembly required a WM498 assembly kit to unite the assembly components. The WM 498 valves have integral aligning pins on mating surfaces and are held together by two tie bolts that run the full length of the assembly. The tie bolts, O-ring seals, and extra aligning pins are supplied in the WM498 assembly kits. With the exception of the end-mounting units, all of the WM498 series valves have '''straight-through''' supply passages that allow the panel assembly to be fed by a single supply source. To seal the supply passage between two components, the WM498 series is designed with O-ring grooves on supply passage interfaces. Air pressure is supplied to the assembly through a WM498A and cap or a WM498D supply manifold. To mount the WM498A end cap on the assembly, extra aligning pins are required in certain installations. Supplied in the assembly kits, these pins are used to connect the end cap's female mounting surface to another female surface. In this type of installation, two O-rings must be used. The WM498D supply manifold is available either as a series mounting unit (WM498D) or as an end-mounting unit (WM498D1).
