Presentation Transcript

  1. Asahi/America Valve Materials • PVC (Polyvinyl Chloride) (32°F -140 °F.) • Cell Class 12454A-(ASTM D 1784) • CPVC (Chlorinated Polyvinyl Chloride) (32°F -195 °F.) Cell Class 23567A-(ASTM D 1784) • PP (Polypropylene) (-4°F -195 °F.) Cell Class 0210B67272 -(ASTM D4101-92B) • PVDF (Polyvinylidene Fluoride) (-40°F -250 °F.) • Cell Class Type II -(ASTM D 3222-91A) • PDCPD (Polydicyclopentadiene) (-20°F -175 °F.) Plastic Materials

  2. Asahi/America Seal Materials Seal Materials • EPDM- 212 °F • Viton® (FKM)250 °F • Teflon® >250 °F • Aflas® >250 ° • Nitrile-212 °F • Hypalon- 250 °F • Styrene Butadiene Rubber >140 °F • Viflon (FKM-F, FKM-C) 250 °F

  3. Asahi/America Abrasion Tests Akron Abrasion Tests on Plastics & Elastomers Plastics % of Wear Hardness Scale PVC .240 D CPVC .514 D PP .550 D PVDF .182 D Elastomers EPDM .490 A VITON (FKM) .968 A HYPALON(CSM) 1.00 A NITRILE(NBR) .190 A

  4. Asahi/America Seal Materials AFLAS • Tetrafluoroethylene/propylene copolymer • Similar chemical resistance to Teflon • Excellent abrasion resistance • Capable of 400 °F • Viflon F, Viflon C • FKM-F, FKM-C Specialty Elastomers

  5. Asahi/America Physical Properties • UV:Excellent UV resistance in all materials. After 10 years exposure, virtually no decrease in burst pressure & a 5% increase in tensile strength. • Abrasion:Superior abrasion resistance compared to metal valves due to the inherent properties of plastics; smooth surfaces and better absorption of impact energy. • Impact Resistance: Superior impact resistance compared to competitors’ plastic valves . Result of body mass (wall thickness) and little or no voids created in the molding process. Physical Properties

  6. Asahi/America Quality & Design • All valves have a minimum working pressure safety factor of 4 to 1. • Average hydrostatic burst pressure is 2000 psi. • All valves are tested after manufacturing. All valves (except dampers) meet or exceed Class VI Shutoff. All valves have traceability as each is labeled with a manufacturer’s number. All valves can be hydrostatically tested 1.5 x max. working pressure for 10 minutes per ASME B31.1.
