A valve is disclosed for dispensing a flowable material. In one embodiment, a shared bidirectional splitter filter mounted on a circuit board communicates in one direction toward the subscriber over a subscriber line, and communicates in an opposite direction toward the central office. The service bus provides logical isolation between a consumer application and a provider application by exposing a set of interfaces for relaying service request and service response messages between the applications. The compression section has a connector port, or hole, through the section and the frame member.
