Flow Control and Check Valves
These Valves are pressure and temperature compensating type valves and
maintain a constant flow rate independent of change in system pressure
(load) and temperature (Viscosity of the fluid). They Control flow rate of
the hydraulic circuit and eventually control speed of the actuator precisely.
Valves with an integral check valve allow a controlled flow and reverse free
flow.

Sub plates are available. Specify Sub-Plates model from the table above. When Sub-Plates are not used the
mounting surface should have good machined finish.
Min. required pressure difference
■ Instructions
Min. differential pressure between inlet and outlet port is required to obtain the optimum pressure compensation.
It varies according to the flow rate to be set. For details, please refer to the performance curve.
Free flow
Check Valve pressure drops vary with flow rates. If models with check valves are used, see free flow pressure
drop characteristics.
Flow Adjustment
[F G-01]
Loosen locking screw and turn flow adjustment dial clockwise for increase, and anti-clockwise for decrease.
The dial makes about 4 revolutions from zero to full flow and the valve opening is indicated on the revolution
indicator. (Refer to characteristic of “Metered Flow vs. Dial Position”)
After flow adjustment, tighten locking Screw.
[F G-02/03] --- Anticlockwise for increase and clockwise for decrease.
Line Filter
To carry out flow adjustments by as small degree as 2 L/min. or less, be sure to use a line filter, 10µ or less, near
the valve inlet.

multiply by the factors in the table below.
2. For any other specific gravity, use the formula :
∆P'=∆P
