All solid thermoplastic butterfly valves sizes 1-1/2"thru 14" shall be of the TYPE 57 lined body designand bubble-tight seal (meeting or exceeding Class VIas defined by American National Standard Institute)with only the liner and disc as wetted parts. Thelever handle (sizes 1-1/2" thru 8") shall have amolded provision for a padlock. Gear operatorsshall be worm gear design, self locking Plasgear.The spherical disc design for higher Cv values shallbe of solid, abrasion-resistant plastic. Liner shall bemolded and formed around the body, functioning asgasket seals with convex ring design on each side ofthe valve for lower bolt tightening torque and valvebody shall have molded body stops and seat reliefarea to prevent over tightening of mating flanges.Stem shall be of 316/403 stainless steel, nonwetted, have engagement over the full length of thedisc and be locked into valve body by PP stemretainer. Valves shall have a molded ISO bolt patternon top flange for actuator mount. PVC shallconform to ASTM D1784 Cell Classification12454-A, PP conforming to ASTM D4101 CellClassification PP0210B67272, and PVDFconforming to ASTM D 3222 Cell Classification TypeII. All PVC PP and PVDF body valves shall be ratedto 150 psi at 70 degrees F, sizes 1-1/2 thru 10”and 100 psi for sizes 12” and 14”. Butterfly valvesshall be wafer style, as manufactured byAsahi/America Inc.
