Super Safety Valve Sub-surface safety valve

The Super Safety Valve is controlled by two hydraulic lines and contains a chemical injection port.  It is designed to close by spring force but has a nitrogen charge chamber to quicken the closing time.  This feature gives the valve the ability to cut wireline and coiled tubing without the addition of balance line pressure.  The valve is held open by maintaining hydraulic control pressure on the control line.  The nitrogen charge chamber and the balance line chamber are the same chamber.  The nitrogen pressure acts directly on the operating piston and a floating check valve keeps the nitrogen from escaping from the chamber into the balance line.  The check valve floats on the surface of the water (or hydraulic fluid) as fluid is pumped into the chamber. When the fluid is removed, the floating check valve sets down on the seat and seals the nitrogen charge in the chamber.
