Note
(1) The soft start-up valve is of the air return method.
(2) As the withstand pressure refers to a pressure range that does
not cause breakage with danger, do not apply a pressure
exceeding the maximum operating pressure range.
Failure to follow this instruction may lead to a malfunction or air
leakage.
(3) This occurs when the duty ratio is 50% and no load is applied.
(4) Impact resistance
- The product must not malfunction in an impact test that uses a
drop tester.
- No malfunction when the test is performed once each in the
axial/vertical directions of main valve and armature in energized
and de-energized conditions.
- Vibration resistance 45 to 2000 Hz
No malfunctioning in a single scanning
- No malfunction when the test is performed in the axial/vertical
directions of main valve and armature in energized and de-
energized conditions (the valve is in the initial state).
(5) The weight indicates the weight without M12 connector cable.
Weight of M12 connector cable (for 2 pcs.) = 0.4 kg
(6) The B10D value is predicted based on the life test conducted in
the SMC's test conditions.
(7) Refer to Section 10.5 of "Specifications" for details.
(8) This product is a pilot type solenoid valve with large flow rate.
Note that if the operating pressure drops to 0.25 MPa or below
because of pressure drop caused by an insufficient air supply
capacity, the valve may not be appropriately switched.
