1 Table TE-/E Complementary safety valves with /FC mechanical microswitches confming to Machine Directive 6/4/CE -6*/FC -6*/FC DPHI-7*/FC These valves are provided with FC mechanical microswitch f the spool position monit and they are designed to fulfil the safety criteria imposed to machine manufacturers by the European Machine Directive. In addition to the nmal function they supplies an electrical on-off output signal indicating the position of the spool/poppet of the valve. The safety function perfmed by the valve is to cut off the hydraulic power line in case of emergency condition, avoiding dangerous movements of the machines actuats. The spool position signal infms the machine controller about the open intercepted status of the hydraulic line. These valves are available in direct and piloted execution and they keep the same hydraulic and electric characteristics of standard products from which they are derived. Classic example of application: on presses on blow moulding machines the safety valves are used to shut off the fluid energy to one me actuats as a consequence of the opening of a mechanical safety device ( gate ) as a consequence of an emergency stop command. The components shown on this technical table are CE marked and certified by TÜV, in accdance with the technical safety requirements provided in the Machine Directive 6/4/CE but not included in the safety components of annex IV. F details about the applicable EN standards, see catalog on line page, section P, table P4. MODEL CODE OF DIRECTIONAL CONTROL SAFETY SOLENOID VALVES Type of solenoid valve = direct, size 6 (see tab.
