ABSTRACT:
The invention is of a valve member having a replaceable deformable insert installed in a groove of the member and a deformable backup member secured to the valve member, preferably by bonding, and abutting so as to abut at least a major portion of a transverse surface of the insert opposite a tapered seating surface thereof. The insert may be of harder more wear resistant material than the backup member extending service life and permitting easier repair or replacement of the insert.
