宝德BURKERT电磁阀带有相应的塑料外壳和一个具有 PTFE 涂层的隔膜。此设备可无需电流借助弹簧力关闭。接通时,宝德BURKERT电磁阀磁芯受到吸引,由此克服弹簧力。阀门特别适合流量很小的、液态或气态的侵蚀性介质。 Technical data Body material ETFE (TEFZEL) Seal material PTFE with EPDM - PTFE with FKM Media PTFE/EPDM: alkalis, acids to medium concentration, washing- and bleaching lyes PTFE/FKM: oxydizing acids and substances, salt solutions, oils and waste gases Medium temperature -10 ... +70 °C Max. ambient temperature max. +55 °C Max. viscosity 21 mm2 /s Response times opening closing approx. 20 ms approx. 20 ms Installation as required, but preferably with solenoid system upright Operating voltages 12 V DC, 12 V DC battery, 24 V DC, 24 V UC, 220-230 V UC Voltage tolerance ± 10 % Power consumption 4 W Duty cycle 100 % continuously rated Cycling rate up to 300 c.p.m. Protection class with cable plug IP 65 Electr. connection Delivery standard: Cable plug DIN 43 650 Form B, 0-250 V.
