No leakage inside due to the elastic seal;2. Streamlined runner and small pressure loss3. No need of packing, then no outward leakage4. Parts above the diaphragm such as bonnet, stem, etc can not be eroded by medium, for the diaphragm cut off the connection between medium and bonnet.5. Replaceable diaphragm and low maintenance cost6. Various lining materials to choose for different medium, and good anti-corrosive.ParameterofG41 Cast iron ptfe diaphragm valve Model PN(MPa)Pressure (Mpa)Applicable mediumWorking TemperatureShell TestSealing TestEG41J-60.60.90.66Non-corrosive fluid≤100ºCEG41J-101.01.51.1Generally corrosive fluid≤85ºCEG41J-1161.62.41.76Strong acid, alkali and various organic solvents (Exclusive of molten alkali metal and elemental fluorine)≤150ºCEG41J-160.60.90.66EG41J-1101.01.51.1Main Parts ofG41 Cast iron ptfe diaphragm valvePart Namevalve BodyDisc and CoverValve StemDiaphragmHandwheelMaterialHT200 Lining RubberHT20035Various basic-type rubbersHT200MaterialHT200 Lining fluorine plasticHT20035Fluorine PlasticHT200MaterialHT200HT20035Natural rubberHT200Pressure-Temperature Level
