| 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. | ||||||

| 139 | Valve | US13633290 | 2012-10-02 | US09206668B2 | 2015-12-08 | Carl Richard Wood |
| A valve has a moveable member movable between open and closed configurations and a cutting device arranged to shear against an anvil member when moving between the open and closed configurations and 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. During opening and closing the sealing member is displaced away from the cutting device 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. | ||||||
