A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular manifolds allows for expansion or modification of the manifold assembly to control a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

A filtering device for removing dirt particles and contaminants from a plastic melt is disclosed. The filtering device includes a housing having a filter chamber, an inlet for feeding plastic melt, an outlet for channeling plastic melt out, and a dirt outlet for discharging dirt particles from the housing.
