*2: Impact/Vibration Resistance (m/s2)300/50

*1: The single type is designed to operate when return pressure is supplied through the supply port {1(P) port}. So make sure supplied pressure is within the operating pressure range.
*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 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)
