1 Solenoid Valve Features 2 For DC power supply 3 For C power supply These models realize high-pressure large-flow-rate control at 35 MPa {35 kgf/cm 2 } and 1 L/min (2) or 16 L/min (3). They are best suited to integration into European Safety Standard (CE) compliant equipment since they have dust-/water-proof properties that satisfy the IEC Pub529 IP65 ingress protection grade.

Standard solenoid valves with a surge killer (option code "N") are very effective to eliminate sparks. However, adequate consideration should be given to the service life of the relay to avoid contact welding due to inrush current at solenoid excitation. In applications where contact welding due to inrush current is expected, solenoid valves with a surge killer (with resistance) (option code "NR") are effective. Note, however, they are not as effective as standard solenoid valves with a surge killer (option code "N") in terms of elimination of sparks. When using solenoid valves without a surge killer, adequate consideration should be given to protection against the reverse surge voltage generated at demagnetization of the solenoid. (It is advisable to incorporate a surge absorbing element such as a varistor in the circuit.) -19

9 Handling Wiring guide for solenoid (C solenoid valve) Solenoids can be used with both 5 and 6 Hz. Drainage When adopting a spool type/operating method (2, 2B, 2N or 2D) that does not incorporate flow at the tank port, connect drain piping from the tank port. Fixed throttle valve It is possible to insert a fixed throttle at port P,, B, or T. However, when fitting a throttle, be careful to maintain the pressure difference before and after the throttle at no greater than 21 MPa {21 kgf/cm 2 }. When inserting a fixed throttle at the tank port, maintain the back pressure at the tank port within the permissible back pressure. Operating force for manual operation pin The force required to operate the manual operation pin varies depending on the back pressure in the tank line.
