| A valve apparatus (10) comprises a housing (12) defining a flow path (14), a valve seat (42) located within the housing (12) around a periphery of the flow path (14), a carriage member (16) located within the housing (12), a cutting arrangement (28) mounted on the carriage member (16), and a valve member (32) mounted on the carriage member (16) via a connection assembly (34) which permits relative movement between the valve member (32) and the carriage member (16). The carriage member (16) is moveable from a first position towards a second position to drive the cutting arrangement (28) across the flow path (14) and to move the valve member (32) into a position in which relative movement between the valve member (32) and the carriage member (16) permits the valve member (32) to sealingly engage and disengage the valve seat (42) to control flow along the flow path (14). | ||||||
| 103 | METHOD OF CUTTING A CONTROL LINE OUTSIDE OF A TUBULAR | EP13824954 | 2013-08-02 | EP2880254A4 | 2016-10-19 | FUHST KARSTEN; WONG KEAT HOONG |
| A method of cutting a control line mounted on an outer surface of a downhole tubular that includes providing a cutting tool having a main body, and a cutting head on a lower end of the body that rotates with respect to the body. A cutting blade is on a lower end of the cutting head, which is rotatable by a motor, where the blade is selectively pivoted radially outward from an axis of the cutting head. As the cutting head rotates, the cutting blade orbits within the tubular axially offset from the axis. When the tool is inserted into the tubular, the radial offset of the blade is controlled so it pivots radially outward into contact with the tubular when the blade approaches an azimuthal area proximate the control line. The cutting blade is retracted when its orbit moves it past the azimuthal area proximate the control line. | ||||||

| A valve assembly for wellbore, downhole or intervention operations, such as for subsea wellbore operations includes a rotatable valve member having a passage formed therein. The valve assembly is reconfigurable between a first configuration in which the passage is aligned or alignable with a first conduit, and a second configuration in which the passage is misaligned or misalignable with the first conduit, so as to cut or sever and/or clamp apparatus present in the valve member passage prior to reconfiguration. The assembly is configured to apply a maximum cutting force at a particular phase or stage of the reconfiguration. | ||||||

| An apparatus for assisting an actuator to close a valve has a cylindrical booster housing with a central axis. The booster housing includes an upward facing piston cavity and a downward facing lower cavity with internal threads for selectively coupling with external threads of a piston head of a valve actuator. A bulkhead is formed between the piston cavity and the lower cavity. The bulkhead has an opening for selectively accepting an actuator stem of the valve actuator therethrough. A booster piston is located within the piston cavity. The booster piston has a piston mounting means located on its bottom side for selectively securing a top end of the actuator stem of the valve actuator to the booster piston. The booster piston is moveable upwards in an axial direction to move the valve from a lower open position to an upper closed position. | ||||||

| A technique facilitates valve operations in many applications including well related applications. A valve utilizes a piston which moves along an arc. The valve has an outer housing and an inner housing spaced to create an arcuate pressure chamber which extends along the arc. A piston is mounted in the arcuate pressure chamber for movement along the arc. A hydraulic force or other force may be selectively applied directly against an end of the arcuate piston to shift the arcuate piston along the arc. In some applications, the piston comprises a cutting edge oriented to enable performance of a cutting operation. | ||||||
| 108 | A DOWNHOLE TOOL | EP12843707 | 2012-10-26 | EP2771537A4 | 2015-11-25 | MANSON DAVID |
| A downhole tool mechanism for applying a driving force, such as a cutter tool for cutting a line captured within the tool, comprises a resiliently compressible member for storing a compressive force; a retaining device for maintaining storage of the compressive force until released; a trigger mechanism for releasing the compressive force when the trigger mechanism is activated. In one form the resiliently compressible member comprises a plurality of concentrically arranged spring washers each having a radial slot therein for receiving a line along the length of the resiliently compressible member. In the cutter form, there is a cutter arranged to cut the line when the trigger mechanism is activated, and the trigger mechanism is activated when the tool receives a shock force to one or both ends. | ||||||

| A rotating gate valve can be used to shear cables or tubing as it closes to obstruct flow. In embodiments, a valve body can have a flow passage and a lateral bore that is transverse to the flow passage. The gate can have a generally cylindrical shape and can rotate about the axis of the gate as it moves laterally to close a flow passage. The lateral and rotational movement can shear articles such as, for example, cables and tubing that extend through the flow passage. | ||||||

A valve typically used in an oil or gas well, having a moveable member such as a ball movable between open and closed configurations and having a cutting device arranged to shear against an anvil member when the ball is moving between the open and closed configurations; and having a sealing member providing a seat for seating of the moveable member when the moveable member is in the closed configuration. The anvil member and the sealing member are moveable relative to one another when the moveable member is moving from the open to the closed configuration, so that during opening and closing the sealing member is displaced away from the cutting device (typically the inner surface of the bore) as the cutting device engages the anvil member. The sealing member is pushed away from the moveable member and the anvil to a maximum separation from the movable member at the point on the stroke when the cutting surface of the moveable member is moving past the anvil member, so that the sealing member is moved out of contact with the ball when the cutting surface engages the anvil member, and moves back into contact with the ball when the cutting surface has passed the anvil member and the sealing surface of the ball is aligned with the sealing member.
