Valve assembly, with a number of gate valves in their housings, has housing surfaces butting together and a working channel over/under the gate valves to give a reduced height and a flat structure

摘要

The valve assembly (1), for fluid inflows and outflows, has a number of valve units (2) each within a longitudinal housing (5) with a holder (23) for a gate valve (24). The longitudinal sides of the valve units have surfaces (25a,25b) which butt together. A working channel (43b) is through each valve housing from the gate valve holder to a connecting surface coaxial to the holder, past the holder over or under it. The channel is partially formed by a groove recess (46a,46b) in the housing butting surfaces
