EDG – 01
Product Description
  • This valve consists of a small DC solenoid and direct-acting relief valves. It serves as a pilot valve for a low flow rate hydraulic system or a proportional electro-hydraulic control valve and controls the pressure in proportion to the input current. Note that this valve is used in conjunction with the applicable power amplifier.

  • Tank-Line back pressure
    Check that the tank line pressure does not exceed 0.2MPa (2.0kgf /cm²)
  • Vent Control
    When this valve is used as a relief valve or for other valve vent control purposes, use 6 mm ID, 300mm long or shorter pipes for piping connections, If pressure instability is encountered, provided a 1-1.5mm diameter orifice for the relief or other valve vent port.
  • Circuit Pressure Control
    When circuit pressure is directly controlled by this valve, make sure that the trapped oil volume is exceeding 40cm3.
  • Low Flow Rates
    The preset pressure may become unstable. To avoid such pressure instability, the flow rate should not be lower than 0.3 L /min.
  • Safety Valve Pressure Setting
    The safety valve pressure setting at the maximum flow rate is preset to a level that is 2MPa( 20.4kgf /cm² ) higher than the pressure adjustment range upper limit. If the operating pressure upper limit is low or a different flow rate upper limit is used, make adjustment after calculating the safety valve pressure setting from the following equation; Pressure setting=(Operating pressure upper limit )+(Additional pressure indicated right )
