* Note: Step response is typical value for a supply
pressure of 7MPa (71kgf/cm2) and uid temperature of 40°C (kinematic viscosity:
40mm2/s).
HANDLING:
1. The amplifier and valve have been
adjusted to match at the factory.
2. Install
position: Horizontal.
3. In the case of 3-port applications
and for the direction that throughflow is most common, use of the following
flow is recommended P→A→B→T.
P→A limit differentialpressure is greater than
that of P→B.
4. Be sure to perform sufficient
flushing before a testing run.
5. Use steel piping for this valve and
the main actuator, and keep piping as shortas possible.
6. There is no air bleeding.
7. Mineral oil hydraulic operating fluid
isstandard. Use an R&O type and wearresistant type of ISO VG32, 46, or 68
or equivalent.
8. Cleanness
of the operating Oil should be apply to Nas 9 or cleaner level.
9. Electrical
wiring between the amp and valve should be no longer than 30 meters. For the
solenoid valve use VCTF 2mm2 2-conductor shielded wire, and for the
differential transformer use VCTF 0.5mm2 4-conductor shielded wire.
10. After
disassembling the valve, be sure to fill the inside of the guide with
operatingfluid before reassembling. Tightening Torque : 5 to 7N · m (51 to
71kgf · cm)
