The present invention provides a mechanically operated traveling valve for use in a sucker rod pump. The valve includes a cylindrical housing, a base positioned in the bottom of said housing which contains a first portion of a sliding shear seal, and a piston positioned within said housing above said base which contains a second portion of the sliding shear seal. The valve is operable between open and closed positions by reciprocal action of a sucker rod on the piston which opens and closes the sliding shear seal.
