Table EY/E Safety cartridge valves with poppet position monitoring ISO standard, onoff, poppet type, conforming to Machine Directive //EC certified by LIFI*/NC 1 RNE OF VLVE S MODELS LID*/FV Inductive proximity sensor FI Inductive position switch FV Sensor electric connector (supplied with the valve) LIDS*/FV Safety cartridge valves with poppet position monitoring, CE marked and certified by TÜV, in accordance with safety requirements of Machine Directive //EC. LIFI: intermediate safety element with FI inductive proximity sensor, to be coupled with functional covers LID: safety valve with integral cover design and with FV inductive position switch, available with optional solenoid pilot valve (LIDH) LIDS: active pilot operated safety valve with FV inductive position switch, available with optional solenoid pilot valve (LIDSH), see section 1 for sensors technical characteristics. These valves are normally used to cut off the hydraulic power line in case of emergency condition, thus avoiding dangerous movements of the machines actuators.
