1. Air Bleeding
To enable proper pressure
control, loosen the air vent when starting up the pump in order to
drain any air from the pump, and fill the inside of the solenoid with
hydraulic operational fluid. The position of the air vent can change by
loosening the M4 screw and rotating the cover.
2. Mounting Method
on a vertical surface causes minimum pressure to increase by 2 kgf/cm2
Pressure Adjusting Screw
initial adjustment or when there is no input current to the valve due
to an electrical problem or some other reason, valve pressure can be
increased by rotating the manual adjustment screw clockwise
(rightward). Normally, the manual adjusting screw should be rotated
back fully to the left (counterclockwise) and secured with the lock
Relief Flow Rate
flow rate can cause setting pressure to become unstable. Use a flow
rate of at least 0.3 l/min.
When using this valve to
control direct circuit pressure, make sure the load volume (P port side
volume) is at least 40 cm3.
Accessories (Valve Mounting Bolts)
M5 x L45
(4pcs) Tightening torque: 51~72 kgf/cm2
7. Use an
operating fluid that conforms to the both of the following
Oil temperature: -20 to
70°C. Viscosity: 12 to 400 mm2/s.
The recommended viscosity
range is 15 to 60 mm2/s.
