1.0″ IPOCV-1 Check Valve

Every gas lift valve is attached to a reverse flow check when being installed on the mandrel. The purpose of this check is to prevent backflow from transferring from the tubing into the casing while gas is being injected into the well. Check Valves and their components are made with stainless steel, or premium material to prevent corrosion. The check dart is pressed against the seal until a differential in pressure is felt above the dart, preventing backflow into the casing.
