Precautions

  • *When energizing valves for a long period of time, heat generated by the coil will cause the temperature to rise, decreasing valve performance, decreasing the lifespan and adversely affecting nearby peripheral equipment.
  • *When energizing a valve continuously, be sure to use the standard type (0.4 W) at an ambient temperature of 40°C or less and pay attention to discharging heat.
  • *Temperature increases are particularly high when simultaneously energizing 3 or more neighboring stations for a long-period continuously or when simultaneously energizing the A side and B side of a dual 3-port valve for an extended period.
  • Be sure to read the individual product cautions before use.
  • See the SMC catalog for product information other than that detailed above.
