*1: Use dry air to prevent condensation when operating at low temperatures.
*2: Vibration resistance: No malfunction occurred under any of the conditions tested in a one-sweep test between 8.3 to 2,000 Hz. Test was performed in axial and orthogonal directions to the main valve/movable armature at both energized and de-energized states. (Value at the initial state)
Impact resistance: No malfunction resulted from the impact test using a drop impact tester under any of the conditions tested. The test was performed once for each set of conditions, in axial and orthogonal directions to the main valve/movable armature at both energized and de-energized states. (Value at the initial state)
*3: If a throttle (nozzle, etc.) is mounted on the outlet side piping, the pressure differential when ON is smaller. Ensure that the pressure differential does not drop below 0.01 MPa.
*4: JIS8375 (at supply pressure of 0.5 MPa) (Numerical value of response time varies according to pressure and quality of air.)
