CEMENT FLOAT SHOE WITH DOUBLE VALVE
PRODUCT NO.: WC-30102
WELLCARE Oil Tools, Double Valve Float Shoes allow operator to maintain a constant fluid height inside the casing of a well. As fluid is allowed to enter through the bottom of the casing, the system maintains a constant differential pressure between the inside and outside of the casing at the floats to ensure constant fluid height within the casing.
A spring-loaded valve in the fill-up unit regulates filling.
When hydrostatic pressure outside the casing exceeds the spring tension, fluid is allowed to enter the casing; when pressure inside the casing combines with spring tension to exceed the pressure outside the casing, the valve closes
