Abstract
A valve body for use in cementing, fracturing or acidizing operations in well drilling with improved wear resistance to extend the operating life of the valve. The valve includes a hardened metal valve head having urethane legs replaceably attached to the valve head. A urethane valve insert may also be provided to facilitate sealing engagement with the valve seat. The urethane legs reduce the overall weight of the valve to reduce the mass of the pumping valve against the valve seat thereby extending the life of the valve. The valve legs are attached to the valve head through fitting engagement and can be replaced and/or repaired.
