Contact SupplierDifferential Fill-up Float Equipment allows 90 per cent casing fill-up during run-in, reducing surge pressures caused by the piston effect of running casing in restricted IDs. Use of Differential Collar with Shoe provides additional buoyancy by allowing only 81 per cent casing fill-up further enhancing draw works efficiency. Circulation can be established at any time while running in. Dropping a ball converts the Differential Valve to a regular Back-Pressure Valve. When Collar and Shoe are run together, dropping one ball converts both units.
