Contact SupplierThe equalizing check valve choke is a top No-Go wire-line retrievable tool which controls upward flow and prevents downward flow. It is landed and set in the F Type landing Nipple. An integral, erosion resistant, ceramic orifice is sized to control the upward flow as desired, while downward flow is checked with a ball and seat device. Pressure can be equalized across the valve by breaking the equalizing plug.
