Flow control valves
Variable throttle valve
This valve controls flow by changing the cross-sectional area through which fluid flows. If the pressure difference between the IN and OUT ports varies, the flow that passes through the throttle varies.
The valve is appropriate in applications where the pressure difference between the IN and OUT ports is small and slight variations in flow are permissible.
Flow control valve
This valve controls flow by changing the cross-sectional area through which fluid flows. Since it incorporates a pressure compensation mechanism, the flow is kept constant even if the pressure varies at the IN and/or OUT port.
When equipped with a check valve, this valve allows reverse flow of compressed fluid.
Flow control valve with shut-off valve
1. The valve is compactly designed and is suitable for feed control of single-purpose machine tools and automatics.
2. Since the valve incorporates a pressure compensation mechanism, it keeps the controlled flow constant regardless of the pressure variation at the IN and OUT ports. If a valve equipped with the temperature compensation mechanism in addition to the pressure compensation mechanism is used, the valve can keep the controlled flow constant even if the fluid temperature (viscosity) varies.
3. The flow is controlled almost in direct proportion to the division on the flow adjusting dial.
