ABSTRACT:
A non-wearing washer for fluid valve is non-fixedly mounted between washer retainer means disposed at a bottom end of a valve stem and the valve seat. The washer is retained in its operative position by configuring its top end to non-fixedly engage the washer retainer means while a tongue portion disposed on the underside of the main washer body is sized to extend down into the valve fitting end which attaches the valve to the discharging end of the fluid pipe. As the washer in non-fixedly mounted in between the bottom end of the valve stem and the valve seat, the rotation of valve stem 20 which translates into relative longitudinal displacement of the valve stem from the valve seat is not translated to the washer, thus eliminating the rotational wear now commonly associated with such washers.
