A valve insert comprises a bushing assembly, a piston assembly and a spring. Its design prevents non-longitudinal movement of the piston assembly as it is moved within the longitudinal bore of the bushing assembly. This virtually eliminates the bell clapper effect commonly suffered by many of the valve inserts currently used in the industry. The design of the valve insert also avoids the pressure imbalances inherent to the prior art valve inserts. The valve insert is designed to fit snugly and sealingly within a suitable borehole, such as the fill and cut-out boreholes of an ECP manifold assembly.
