Patent number: 5135032Abstract: A slurry gate valve incorporating dual gates for the positive interruption of fluid flow through a pipeline associated with the valve. The dual gate valve is movable through three positions: a fully open position, a half open position, and a full closed position. The valve includes a main leader gate and a follower gate each having selectively alignable fluid passageways. An interlock mechanism selectively connects the dual gates for simultaneous travel once the gates have reached the half open position. The dual action gate valve reduces wear on the downstream resilient seals associated with the valve by shielding the seal against the fluid flow through the main passageway of the valve.Type: GrantFiled: August 14, 1991Date of Patent: August 4, 1992Assignee: Foster Valve CorporationInventor: Glenn C. Parks, Jr.

Patent number: 5090661Abstract: Gate valve having a primary seal, actuated by fluid pressure in the flow conduit, for preventing leakage along the gate member on the upstream side of the gate valve and a secondary seal actuated by fluid pressure upon leaking of the primary seal and including a self-actuating relief means to prevent build-up of fluid pressure in the valve body in excess of the pressure in the flow conduit.Type: GrantFiled: September 28, 1990Date of Patent: February 25, 1992Assignee: Foster Oilfield Equipment Co.Inventors: Glenn C. Parks, Jr., C. Mack Ellison, William L. Godare, John Beson

Patent number: 4444404Abstract: A blowout preventer and a seal are disclosed for sealing about pipes or other objects in a well bore. The seal element is a semi-circular section of resilient compressible material having a semi-circular inner surface to engage the pipe and embedded radially disposed support elements having anti-extrusion members which serve in combination with overlapping ram block members to prevent extrusion of the resilient material from the top and bottom of the seal. The top and bottom anti-extrusion members are stair stepped and have interlocking fingers and recesses and are adapted to slide radially and circumferentially with an adjacent anti-extrusion member element as the elements move toward or away from the pipe in the well bore. Flanges on the seal element are provided with top and bottom plates each of which overlaps at least one support element.Type: GrantFiled: October 19, 1982Date of Patent: April 24, 1984Assignee: Hydril CompanyInventor: Glenn C. Parks, Jr.
