HANDLING:
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 insideof 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 : Mounting on a vertical surface
causes minimum pressure to increase by 2 kgf/cm2
(0.2 Mpa).
3. Manual Pressure Adjusting Screw : For the 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 nut.
4. Please minimize the oil pressure in the return line,
and make sure that the output of independent tube must be under the oil surface
in the tank.
5. Minimum Relief Flow Rate : A small flow rate can
cause setting pressure to become unstable. Use a flow rate of at least 0.3
l/min.
6. Load Capacity : When using this valve to control
direct circuit pressure, make sure the load volume (P port side volume) is at
least 40 cm3.
7. Use an operating fluid that conforms to the both of
the following.
Oil temperature: -20 to 70°C.
Viscosity: 12 to 400mm2/s.
The recommended viscosity range is 15 to 60mm2/s.
