Abstract: A backup stem seal for a gate valve retains pressure in the body when the valve is in the closed position. The backup seal is secondary to the main stem seal assembly in the bonnet. It features metal-to-metal contact between surfaces that are radially oriented or sloping and further can contain a retaining groove for a seal ring in one or both the opposed metal-to-metal surfaces. The groove can be formed to better retain the ring from damage from flowing fluids when the valve is open. A passage through the bonnet may be used to test for leakage past such seal. The backup seal allows maintenance of the main stem seal without removing the valve from service.

Abstract: A low pressure backseat sealing apparatus having a flexible sealing lip which contacts the backseat prior to contact between a stem shoulder and the backseat, with the stem shoulder positioned above the flexible lip, thereby limiting stem movement while allowing internal valve pressure to achieve a seal between the flexible lip and the bonnet.
