The LiMAR Back Pressure Valve is designed to allow the Coiled Tubing String to remain full of fluid in applications where there is a large difference in hydrostatic pressure between the workstring and the well-bore.
The tool features a normally closed valve which prevents flow from the CT string to the well-bore. The opening pressure of the valve can be easily adjusted without disassembly to ensure the desired operating pressure is set prior to RIH. As the Coiled Tubing string pressure is increased to the pre-set level the valve will open to a large bore and allow the string contents to be pumped into the well-bore.
