A plurality of manifold valve assemblies each including pairs of generally vertical valve cylinders each cylinder having actuator rods that are coaxial with each other, the rods being independently actuatable by their respective actuators. Each cylinder has an inlet port at its top each connected to a different supply conduit and each being connected by a crossover conduit near its lower end to the lower end of the other cylinder of the pair. One of the bottom ports of each pair is connected to a drain, thereby forming a leak detector, while the other bottom port of each pair is connected to a line supplying a clean-in-place liquid. Valve seat 45 is positioned below valve plug 40 so that it is closed by extension of actuator rod 32.

A manifold valve assembly, comprising: a plurality of supply conduits each supplying a different fluid, a plurality of distribution conduits for distribution of said fluids to a plurality of destinations, a plurality of valve assemblies each including a pair of generally vertical valve cylinders each cylinder having an upper valve and a lower valve actuated by a pair of actuator rods that are coaxial with each other, the rods being independently actuatable by independently controlled actuators, one valve cylinder of each of said pairs having an inlet port connected to a supply conduit and the other valve cylinder of each of said pairs being connected to a distribution conduit, the valve cylinders of each pair being connected to each other by a crossover conduit near the lower ends of said cylinders, one of the bottom ports of each pair being connected to a drain, thereby forming a leak detector while the other bottom port of each pair is connected to a line supplying a cleaning fluid.
