Well testing DST Super Safety Valve

Sub-surface control downhole super safety valve 8"

The Safety valve normally run inside or below a BOP and is used to control well flow.

The valve is controlled by two hydraulic lines and contains a chemical injection port. Designed to close by spring force but has a nirogen charge chamber to quicken the closing time which gives the valve the ability to cut wireline and coiled tubing without the additon of balance line pressure. The valve is held open by maintaining hydraulic control on the control ine. 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 hydrulic 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.
