WIDE RANGE OF MODELS - Choose the optimum valve to meet your needs from a large selection available.
The DSG-03 50 series solenoid operated Directional valves are classified into two basic models: Standard type ------- Useable at high pressure, high flow [315 Kgf/cm2 120 L/min] Shockless type ------- which greatly reduces noise which is a result of spool changeover and vibration in pipes. The optimum valve for any system can be utilized since many spool types and various solenoids are all available, along with other optional functions.

Maximum flow rates at 50 Hz solenoid with serviceable voltage range refer to the figures in the upper column and 60 Hz solenoid within serviceable voltage range refer to the figures in the latter column. Where two figures are shown in the same column, the figure outside ( ) is at rated voltage and inside ( ) is at the minimum permissible solenoid voltage. (Example)
At the rated voltage (50 Hz) Regardless 50Hz or 60 Hz serviceable voltage range 60Hz, 100% V At the rated voltage (60 Hz) 50Hz, 80% V At the Minimum permissible voltage (50Hz)
