Product Description
Full Open Safety valve
Applications---Full Openg Safety Valve(FOSV)
The DR 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. After weight material is added to the mud, the kelly can be reconnected, the safety valve opened, and circulation initiated.
Like the kelly valve, the 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.
The DR two-piece safety valve offers the convenience of a two-piece body for easy maintenance. Its full bore also allows the unrestricted flow of drilling fluid reducing wear on critical parts while providing unrestricted access for downhole tools.
Connection Flexibility
Safety valves can be provided with tubing connections. Special threads are available upon request.
The DR safety valves are 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.
When ordering please specify:
1. Connection threads,
2. O. D. And I. D.
3. Working pressure
