*1: Use dry air when operating at low temperatures. No condensation.
*2: Vibration resistance: No malfunctions occurred in a 1-sweep test between 45 and 2,000 Hz. The test was performed in both energized and non-energized states and in the axial direction and at right angles to the main valve and armature. (Initial value)
Impact resistance: No malfunctions after testing using a drop-type impact tester under the following conditions: in the axial direction and at a right angle to the main valve and armature in both energized and non-energized states (once for each condition state).
*3: Values for high-speed response type.

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.
