  • Modular stop for valve
    Patent number: 9726295
    Abstract: A modular stop is provided for ball valves, such as those used as drill stem safety valves. The modular stop can be a replaceable component in valves for use with stems used to rotate a ball valve in the valve's body. The modular stop can bear the wear associated with the operation of ball valves and when the modular stop has exceeded its usable service life, it can be replaced without replacing the whole of the valve body. The modular stop can be used in new valve manufacture as well as in the retrofitting or remanufacturing of existing valves.
