Standard valve sealing is EPDM, on request other elastomeric compounds or metal seated valves aresupplied.The chart below shows the standard material combination and codes:The following indicated suffixes denote the sealing valve material:B=BUNA N; V=VITON*; T= PTFE; M=METAL - VITON is a registered Trade Mark of DUPONT NEMOURS.Observe the elastomeric temperature Design limitations:BUNA N = 110ºC; VITON= 160ºC ; PTFE=200ºC; METAL= 400ºCA number of options can be manufactured on request depending on their construction design.Materials:All PTFE made valves (Code CT-TT-T); BUNA N coated flap material (Code CN-CB-B), polished mirror stainless steel material for hygienicduties; Exotic materials such as MONEL, HASTELLOY B, HASTELLOY C, TITANIUM…Spring loaded Valve designs:Valves supplied with spring loaded plate on request. The desired opening pressure must be indicated in the requirement.Manufacture length:DIN 3202 K4, DIN 3202 K5 (new designation EN 558-1)ANSI300Kg***bar***(1).- All measuring units used in the elaboration of this datasheet unless otherwise stated are: Dimensions in mm / Weights in Kgs / Kvs in m3/h / Pressure in barg (1 barg = 0.1 Mpa).(2).- Information regarding the installation, start up and maintenance of equipment can be obtained from the Tech.Dept. and/or the Quality Technical Department.
