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)
