Technical data Working medium: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and diaphragm material. Media temperature: NBR (code 2) PTFE/EPDM (code 54) PTFE/EPDM (code 5M) PTFE/FKM (code 5T) PTFE/PVDF/EPDM (code 71) All pressures are gauge pressures. Operating pressure values were determined with static operating pressure applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing is ensured for the given values. Information on operating pressures applied on both sides and for high purity...
