IMPROVED RESILIENT SEATED GATE VALVE ABSTRACT OF THE DISLOSURE A gate valve structure for use in large diameter mains carrying fluids under high pressure, the gate valve structure being provided with an improved annular resilient seal for engaging a valve seat of the type where the valve seat provides for a face-seal and an edge-seal with intermediate sections making both a face-seal and an edge-seal. The annular resilient seal member is provided with a pair of arcuate bulges oppositely disposed thereon at positions to engage the face-seat surface of the valve seat adjacent the face-seat surface's minimum radial thicknesses to provide an increased contact in this area when the gate member is in the closed position. Additionally, the improved gate valve structure utilizes opposed ribs in the elongated chamber of the casing, the ribs being received in guideways or recesses in the periphery of the gate member so as to guide the gate member during opening and closing. Such an arrangement permits the use of smaller and lighter valve casings for large diameter mains.
