  • Valve-to-fitting converter for process piping systems
    Patent number: 7775234
    Abstract: Valve-to-fitting converter that mounts on the body of an existing valve in a piping system in place of the actuator for the valve and has a dam that mates with a weir in the valve body to block flow between sections of piping connected to the valve body, and ports that provide communication between the sections of piping and fittings connected to the converter. With such converters replacing two or more of the valves in a system, sections of piping can be isolated and/or re-routed without having to shut down the entire system for an extended period of time.
