Abstract:
A control valve (10) comprising a plurality of interchangeable valve body modules (12), each module having a main valve cavity (22) and a plurality of separate cross valve communication ports (26a-d) communicating; and at least one interchangeable gasket (14) disposed between adjacent modules and configured to individually communicate the main valve cavity and the communication ports between adjacent valve body modules, wherein the gasket is further configured to selectively communicate between the main valve cavity and a selected one of the cross valve communication ports. In one embodiment, each valve body module further includes a passage (30) communicating with the main valve cavity. In this case, the gasket may be configured to selectively communicate between the passage and the selected one of the cross valve communication ports, thereby selectively communicating between the main valve cavity and the selected one of the cross valve communication ports through the passage by selective orientation of the gasket.
