| Fluid | Air | |
|---|---|---|
| Operating Pressure Range (MPa) | VZA4121, 4141 | 0.15 to 1.0 |
| VZA4221, 4321, 4421, 4241, 4341, 4441 | 0 to 1.0 | |
| Pilot Pressure Range (MPa) | VZA4121, 4141 | 0.15 to 1.0 |
| VZA4221, 4321, 4421, 4241, 4341, 4441 | 0.1 to 1.0 | |
| *Impact/Vibration Resistance (m/s2) | 150/50 | |
However, pilot pressure must be greater than or equal to operating pressure
*Impact resistance: No malfunctions after testing using a drop-type shock tester under the following conditions: in the axial direction and at a right angle to the main valve with both pilot signal ON and OFF, once for each condition state. (Initial value)
Vibration resistance: No malfunctions occurred in a 1-sweep test between 8.3 and 2,000 Hz. The test was performed with both pilot signal ON and OFF and in the axial direction and at right angles to the main valve. (Initial value)
