Plug valve features include:
thick one-piece continuous lining that fully covers all wetted surfaces of the valve body and face of flange;
360.degree sealing surface (as much as x10 greater than other lined valve designs) assures drop-tight shut-off;
omni-directional sealing, independent of line pressure;
zero cavity between body lining and plug;
in-line adjustable (to re-seat plug) without disturbing valve installation;
very cost effective vs. high alloy body materials.
