Like the Packard International one-piece KV-1, the two-piece KV-2 provides a positive seal in the event of a kick. The KV-2 can be used as an upper kelly valve, lower kelly valve, safety valve, or mud saver.
Features and Benefits
The KV-2 two-piece kelly valve offers similar functionality to the KV-1 with the added convenience of a two-piece construction for even easier maintenance. Its full bore also allows the unrestricted flow of drilling fluid — reducing wear on critical parts while providing unrestricted access for downhole tools.
The KV-2 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. Special threads are available upon request.
Packard International’s KV-2 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 Teflon and metal sealing system of the ball and seats of the KV-2. 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 under full rated working pressure. The KV-2 is available up to 15,000 psi working pressures (22,500 psi hydrostatic test pressure).
Packard International’s KV-2 is designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.
