DROP-IN RETRIEVABLE CHECK VALVES
Hi-Kalibre Drop-In Retrievable (DIR) Check Valves are a dart type check valve, incorporating a low pressure soft seal over a high pressure metal to metal sealing mechanism. This offers extended service life and reliability over ball type checks. The design of our DIR check valves allows high capacity down hole flow while preventing backflow from the well. The DIR tool is easily deployed or retrieved with provided tooling, and uses standard wire line connections.
