Safety Valves - Direct Operated, Pilot Operated, Cartridge Execution w/ Inductive Position or Prox Switches

Safety valves are designed to fulfill 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 2006/42/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 14 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 www.atos.com, catalog on line, section P, table P004.
