Abstract
A high-pressure float valve for positioning downhole within a well to control fluid flow includes a valve cage having a pair of side seal grooves each for receiving an exterior elastomeric seal therein and a plurality of cutouts provided on the top end of the valve cage. The valve cage can undergo nitride heat treatment and the internal components are made from 1018 hot rolled steel. The dimensions of a Model 5RF plunger-type valve and Model 5RG flapper-type float valve can be modified to meet the high pressure of a 10 ksi rating.
