Check valves are installed in many piping systems. Their purpose is to allow flow in only one direction, which can be critical for plant safety and to protect equipment from damage. There are a few ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

Insertion and tapping valves connect to pipelines without interrupting pipeline service. Insertion valves may interrupt media flow during installation, but they do ...

Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably ...
