The KV-1, Packard International’s innovative, one-piece kelly valve, is designed to provide a positive seal in the event of a kick and can be used as an upper kelly valve, lower kelly valve, safety valve, or mud saver.
Features and Benefits
Approximately half the weight and length of some kelly valves, most of the KV-1s can easily be handled by one person. The compact body design saves space, and its full bore allows the unrestricted flow of drilling fluid — reducing wear on critical parts while providing unrestricted access for downhole tools.
The KV-1 can be provided with left-hand connections compatible with the swivel and upper kelly connections, as well as connections compatible with the lower kelly connections and any mating tool joints. Many proprietary threads are available upon request.
Packard International’s KV-1 is built with enough length on each end to allow fully recutting the connections in the event of damage to the threads or shoulders where sealing takes place.
High and Low Pressure Sealing
High and low pressure sealing is assured by the metal-to-metal sealing of the ball and seats of the KV-1. The ball and lower seat float while the upper seat is fixed in the body. This floating/fixed design aids in low pressure sealing and enables the operator to pressure balance the valve when opening it under partial pressure. The KV-1 is available up to 15,000 psi working pressures (22,500 psi hydrostatic test pressure).
All internal components are H2S resistant. The optional valve bodies comply with NACE standard MR0175.
All valve bodies, internal components, proprietary threads, OD/ID Coating or plating, cold working of threads and other special requests are fully traceable. Certificates are included in data books accompanying the valves upon request.
Packard International’s KV-1 is designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.
