The WN-2 Ball Type Safety Valve is designed to be stabbed into the top joint of drill pipe or tubing at the rig floor and closed quickly in case a well kicks. Safety valves are not designed to rotate in the drill pipe string, rotate on a swivel or pull on a stuck string of tubing.
Like the kelly valve, the WN-2 Safety Valve is full opening. The ball-type design permits the valve to be compact, easy to handle, and yet have great strength. Standard test pressure is 10,000 pounds, but higher pressure ratings are available.
When ordering please specify threads, O. D. and I. D. WNCO SAFETY VALVES are available in virtually any size and configuration our customers may require.
