The valve"opens" as increasing pressure opposes the spring force.Air-to-close valve with fail-safe action: Fail-openThe springs "open" the valve when the pressure acting on theactuator diaphragm is reduced or upon air failure. The valve"closes" as increasing pressure opposes the spring force.SpecificationSpecificationsNominal sizeDN 15 to 150Characteristic» linearLeakage rateClass IVFlangesAccording to DIN 2532Materials × Temperature ranges (WN =   Material Number according to DIN)BodymaterialMaterial of valve diaphragmNaturalrubber (NR)Nitrile(NBR)Butyl(IIR)Butyl withPTFE facingCast iron /rubber linedWN 0.6025–10 °Cto+70 °C–10 °Cto+80 °C–10 °Cto+110 °C–10 °CTo +150 °CStainless steel, WN 1.4581Cast iron / rubber–10 °C to +90 °CCast iron /PTFE lined---–10 °C to+150 °CApplicationFinal control element for dirty, viscous, and extremely corrosive fluids as well as for fluids containing solid matter.
