SECTORS
The DTI Coiled Tubing Hydrostatic Valve supports a column of fluid in the coiled tubing until an increase in pressure, over the pre-set opening pressure, is applied. A controlled amount of fluid is then able to be deposited in the well. Once the required volume of fluid has been pumped the pump pressure is reduced. The valve will them close, and the fluid will cease to flow through the valve.
The DTI CT Hydrostatic Valve features an integral adjuster mechanism, which is activated by removing the locking screws and winding the Upper Connector sub clockwise to increase or anticlockwise to reduce pressure. This feature allows the valve opening pressure to be set without disassembling the tool or removing from the BHA.
The DTI Hydrostatic Valve locking screws also give the tool a torque through capability.
