  1. Asahi/AmericaThermoplastic Diaphragm Valves

  2. Asahi/AmericaDesign Technology for Valves 8 bolts 10 bolts 12bolts The area where Max. distortion is observed 3 pattern analysis 0 Sealing point A point on valve seat minimum distortion 200 Large Analytical conditions • Body U-PVC (1/4 cut model) • Pressure 230 Psi CAE Analysis of Body (Type 72 size 5”) These results show when 10 bolts are applied, distortion of the sealing portion is minimized

  3. Asahi/AmericaDesign Technology for Valves CAE Analysis of body (Type 14-3”) Distortion Stress (Max distortion) ( Max distortion) Analysis Conditions - Pressure ; 285 Psi Ambient temp. Analysis Conditions - Pressure ; 285 Psi Ambient temp. .
