Abstract: 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.

Abstract: A magnetically actuated pop-up drain assembly includes a tailpiece having an upper end, a lower end and a hollow interior. Axially received within the tailpiece interior is a plug including a dome-shaped cap with an elongated stem depending therefrom.

Abstract: The present invention provides lift pin strategies with a reduced risk of causing contamination due to the up and down actuation of lift pins. The present invention provides a lift pin system that uses electromagnetic actuation strategies in order to raise and lower lift pins. The electromagnetic forces act remotely on the lift pins so that direct contact or coupling of the lift pins to actuation components is not required. This avoids contamination that otherwise would be associated with friction and associated lubricants used for mechanical actuation strategies.
