    Abstract: A valve with a packing assembly includes a valve body assembly (12) with a bore, a valve member (17) moveable between an open position and a closed position, and a valve stem (23) coupled to the valve member. A first stem packing (37) circumscribes a portion of the valve stem, and is located in an upper bore portion of the bore. A first packing retainer (41) has a collar that limits axial movement of the first stem packing, and also has a first retainer body defining an inner cavity. A second stem packing (57) circumscribes a portion of the valve stem and is located in the inner cavity of the first packing retainer. A second packing retainer (67) has a neck compressingly engaging the second stem packing, and a retainer shoulder that engages the first packing retainer. A retaining assembly (84) is coupled with the valve body assembly for applying axial force to the second packing retainer.

    Abstract: A valve stem packing assembly (33) can seal a valve stem (29) to a valve body (13) having a body cavity (21). The packing assembly includes a packing ring (71) circumscribing the valve stem within a stem opening extending axially through the valve body. A primary dynamic seal (34A) is positioned to seal a dynamic leak path between the packing ring and the valve stem. A secondary dynamic seal (34C) is spaced axially apart and functionally independent from the primary dynamic seal and positioned to redundantly seal the dynamic leak path. A primary static seal (34B) is positioned to seal a static leak path between the packing ring and the valve body. A secondary static seal (34D) is spaced axially apart and functionally independent from the primary static seal and positioned to redundantly seal the static leak path.

    Abstract: A gate valve (10) for use in oil field applications having a seal assembly (78) made up of an elastomeric case (80) and a spring (88) in the case having a V-shaped cross section. The spring has legs (90) that depend from one another, and free ends (94) of the legs that are contoured towards one another to define a rounded surface (96) on outer surfaces of the legs. The rounded surface reduces stress contact between the spring and the case, thereby prolonging seal assembly life. The seal assembly can be placed between a stem (20) in the valve and a gland packing (12). Other seal assembly locations include between a seat ring (32) and counterbore (34) in the valve body.
