Pilot pressure range graph
| Fluid | Air |
|---|---|
| Operating Pressure Range (MPa) | 0.2 to 0.9 |
| Pilot Pressure Range (MPa) | See the pilot pressure graph below. |
| Ambient and Working Fluid Temperature °C | 0 to 60 |
| *1: Lubrication | Required (turbine oil class 1 ISO VG32 equivalent) |
| Mounting Orientation | Free |
| *2: Impact/Vibration Resistance (m/s2) | 150/50 |
*1: This valve is a lubricated type. Use class 1 turbine oil (ISO VG32).
*2: 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 45 and 1,000 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)
