1/4" BSP or NPT solenoid valve with PTFE body and PTFE seals 2/2 way Normally Closed direct acting 0 to 3 bar rated with 5.0mm orifice Kv flow factor 7.1 Litres a minute based on water with 1 bar pressure drop. The PE220H02 1/4" threaded PTFE dry armature solenoid valve has an isolated core tube so the media is only in contact with PTFE making it ideally suited very aggressive and corrosive acid and alkali media as concentrated Hydrochloric Acid (HCL) and Sulphuric Acid (H2SO4). The PE220H02 PTFE solenoid valve fitted with standard 18.5 Watt (24VA to 33VA) IP65 Class H Nass Magnet 13/36 coil as standard with options for ATEX EExmIIT4 coil for Zone 21 and 22 hazardous area applications. All PE220H03 3/8" PTFE solenoid valves are function, leak and pressure tested. Temperature range: Media -10ºC to +90ºC, Ambient -10ºC to +60ºC available voltages 12vDC, 24vDC, 48vDC,110vDC and 220vDC or 24vAC, 48vAC, 110vAC or 230vAC 50/60Hz.
