Flowserve 40407-1-R19 Industrial Flange Valve

Flowserve 40407-1-R19 Industrial Flange Valve is a flanged-connection valve designed for use in industrial piping systems, where it serves to regulate or isolate flow in process lines and integrates with standard flange interfaces that are common in large-scale plant environments. The unit is identified by Flowserve part number 40407-1-R19, placing it within Flowserve's broad catalog of industrial valves that are designed for compatibility with common piping standards and retrofit projects. Flange valves are installed between standard pipe flanges and bolted in place to create a sealed flow path in process lines, providing a replaceable valve segment that can be serviced or swapped without disassembling upstream equipment. In industrial applications, flange valves commonly serve as isolation devices or as throttling elements, depending on the specific trim and actuation options used in a given installation, which flow control engineers consider when designing piping loops, emergency shut-off schemes, and routine maintenance schedules. Because this item carries a Flowserve model designation, it can be cross-referenced against Flowserve's technical documentation and catalog to determine compatibility with existing flange standards and piping systems, helping buyers verify fit before ordering and plan integration with actuators or automation systems.
