Specifications
| Operating fluid | Air |
|---|---|
| Operating pressure range MPa | +0.15 to +0.7 |
| ^*1) Pilot pressure range MPa | Operating pressure ~ +0.7 |
| Ambient and operating fluid temperatures °C | -10 to +60 (No freezing.) |
| Lubrication | Not required |
| Mounting orientation | Free |
| ^*2) Impact resistance / vibration resistance m/s^2 | 150/30 |
*1) Due to the structure, this product operates when return pressure is provided from the supply port (port 1 (P)); therefore, be sure to supply pressure in the working pressure range to the supply port.
*2) 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 with pilot signal ON and OFF (once for each condition). (Initial value)
Vibration resistance: No malfunction when tested under 45 to 2,000 Hz 1 sweep, axial and perpendicular directions of the main valve / armature, energized and non-energized conditions. (Initial value)
