Abstract
The valve has a pair of mutually rotatable ceramic valve bodies within the bonnet that cooperate to allow a flow of water in one relative position and to block a flow of water in a second relative position. One valve body is engaged by the valve stem to rotate therewith while the second valve body is held fixed within the bonnet via radial projections that fit into recesses in the bonnet. An elastomeric ring of square cross-section is squeezed against the non-rotatable valve body by a spiral retaining ring that is positioned in a circumferential groove in the bonnet.
