20100071790 | DIVERTER VALVE - Provided is a diverter valve including a housing assembly having a plurality of ports and a drum assembly disposed in the housing. The drum assembly including a plurality of passages for selectively coupling the ports, wherein an axial position of the drum assembly with respect to the ports determines which ports are active and which parts are dormant. Further provided is a method of operating a diverter valve, including disposing a drum of the diverter valve in a first position, wherein the first position is configured to provide a first passage from an inlet of the diverter valve to a first outlet of the diverter valve, the first passage comprising a first bend-pipe extending crosswise to an axis of the drum and comprising a first radius of curvature that is at least five times an internal diameter of the first bend-pipe, and moving the drum along the longitudinal axis through the diverter valve to a second position, wherein the second position is configured to provide a second passage from the inlet of the diverter valve to a second outlet of the diverter valve, the second passage comprising a second bend-pipe extending crosswise to the axis of the drum and comprising a second radius of curvature that is at least five times an internal diameter of the second bend-pipe. | 03-25-2010 |
20100171056 | Gate Valve Rotary Actuator - A valve actuator comprising a screw member coupled to a valve stem and a sleeve such that rotation of the sleeve causes translation of the valve stem. The sleeve has a first end that is rotatably coupled to a housing that is fixably coupled to a valve body and a second end that projects out of the housing. The valve stem is partially disposed within the sleeve and extends into the valve body. A transmission is coupled to the housing and engaged with the sleeve. A motor is coupled to the transmission so that operation of the motor causes rotation of the sleeve. | 07-08-2010 |
20110083746 | SMART VALVE UTILIZING A FORCE SENSOR - A valve, in certain embodiments, includes a body having a flow path, a stem, a flow element coupled to the stem, wherein the flow element interfaces with the flow path to regulate flow of a fluid through the flow path, and a force sensor coupled to the stem and configured to indicate an amount of force exerted on the stem. | 04-14-2011 |
20120256111 | SPLIT GATE VALVE - Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal. | 10-11-2012 |
20120286182 | SPLIT GATE VALVE WITH BIASING MECHANISM - A system includes a split gate valve with first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. The split gate valve also includes at least one expansion bar configured to bias the first and second gate sections from one another to seal against opposite seats of the split gate valve, wherein each expansion bar includes a spring mechanism configured to compress upon moving the first and second gate sections into and beyond the closed position to prevent buckling of the expansion bar. | 11-15-2012 |
20130341870 | MULTI-BARRIER SEAL SYSTEM - A multi-barrier seal system, including, a first seal assembly configured to provide a first sealing barrier between an auxiliary line and a mineral extraction system, and a second seal assembly configured to provide a second sealing barrier between the auxiliary line and the mineral extraction system, wherein the second seal assembly is configured to shear through the auxiliary line. | 12-26-2013 |
20140053932 | DIVERTER VALVE - Provided is a diverter valve including a housing assembly having a plurality of ports and a drum assembly disposed in the housing. The drum assembly including a plurality of passages for selectively coupling the ports, wherein an axial position of the drum assembly with respect to the ports determines which ports are active and which parts are dormant. Further provided is a method of operating a diverter valve, including disposing a drum of the diverter valve in a first position, wherein the first position is configured to provide a first passage from an inlet of the diverter valve to a first outlet of the diverter valve, the first passage comprising a first bend-pipe extending crosswise to an axis of the drum and comprising a first radius of curvature that is at least five times an internal diameter of the first bend-pipe, and moving the drum along the longitudinal axis through the diverter valve to a second position, wherein the second position is configured to provide a second passage from the inlet of the diverter valve to a second outlet of the diverter valve, the second passage comprising a second bend-pipe extending crosswise to the axis of the drum and comprising a second radius of curvature that is at least five times an internal diameter of the second bend-pipe. | 02-27-2014 |
