  • in emergency situations to kill the well when used jointly with a packer;
  • in combination with a packer during formation hydraulic fracturing as well as various well operations in the course of well completion and operation.


  • these valves can be used multiply for one tripping operation;
  • proven by years of successful application experience;
  • low price;
  • high repairability.


  • the valve is opened by generating annulus pressure that exceeds the pressure inside the valve and the tubing.


  • Testimonial from “TatneftLeninogorskRemServis” Ltd.
