Flow Control Valves / Flow
Control and Check Valves
FCG-01-4-11 DATASHEET
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. Repeated resetting can be made easily with a digital
readout.
INTRODUCTION
- 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.
Check valve pressure drops vary with flow rates. If models
with check valves are used, see free flow pressure drop characteristics
