DESCRIPTION APPLICATION
- it is used jointly with a packer during a formation hydraulic fracturing and other well operations after which the circulation above the packer is generated hydraulically.
ADVANTAGES
- in emergence cases to kill the well when it’s jointly used with a packer;
- low price;
- high repairability;
- proven by years of application experience.
DESIGN FEATURES
- this valve can be used once during one tripping operation;
- the valve’s actuated when the annulus pressure exceeds the pressure in the interior of the valve and tubing.

1. THE VALVE IS CLOSED
2. THE VALVE IS OPEN
The valve is open after generating the annulus pressure that exceeds the inner tubing pressure. This causes the ring to break, the piston to move downwards and the circulating ports to open.
