Safety valves direct, pilot operated and cartridge execution

Transcription

1 Table E-3/E Safety valves direct, pilot operated and cartridge execution with inductive position or proximity switches conforming to Machine Directive 6/4/CE DHI-6*/FI LIDA-343*/FV LIFI-34*/NC DKE-6*/FV LIDAS-343*/FV DPHI-7*/FV Safety valves are designed to fulfil the safety criteria imposed to machine manufacturers by the European Machine Directive. They are CE marked and certified by TÜV, in accordance with the technical safety requirements provided in the Machine Directive 6/4/CE but not included in the safety components of annex IV. In addition to the normal hydraulic function they are equipped with inductive or proximity switches; with the on/off switch indicates the position of the spool/poppet of the valve. 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. By checking the switch status, corresponding to open or intercepted hydraulic line, the machine controller can perform the safety function. Two versions are available: - FI inductive proximity switch ; - FV inductive position switch (double contacts) ; see section 4 for technical characteristics. Safety valves are available in direct, piloted and cartridge executions, with same hydraulic and electric characteristics of standard products from which they are derived. Typical application is on vertical and horizontal presses to shut off the fluid energy to one or more actuators as a consequence of the opening of the machine gate or as a consequence of an emergency stop command. For details about the applicable EN standards, see catalog on line, section P, table P4.
