FG FCG Hydraulic Flow Control and Check Valves
FG FCG Hydraulic Flow Control and Check 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. Repeated resetting can be made easily with a digital readout.
●Min. required pressure difference
The minimum 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 curves.
● 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 the locking screw and turn the 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 characteristics of "Metred Flow vs. Dial Position"). After flow adjustments, tighten the locking screw. [F*G-02, 03, 06, 10] Loosen the locking screw and turn the flow adjustment handle clockwise for increase, and anti-clockwise for decrease. Open condition is indicated in digital-scale in built-in revolution indicator (Refer to the characteristics of "Metred Flow vs. Dial Position"). After flow adjustments, tighten the locking screw.
● Line filter
To carry out flow adjustments by as small degree as 2L/min (.53 U.S.GPM) or less, be sure to use a line filter of 10 µm
or finer and install it near the valve inlet
