ZS3 series multiple directional control valves

The ZS3 series multiple directional control valves, one kind of combination valves with the manual directional control valves, are mainly used in hydraulic systems of engineering machinery, mining machinery, lifting transportation machinery and other machinery to change flow direction for integrated control over several actuator.
The ZS3 series multiple directional control valves are designed on the basis of the former ZS series, not only succeeding the advantages of the ZS series multiple directional control valves, but also including fine speedregulating function, which means that the work flow rate will increase or decrease respectively with spool movement when the spool is moving within the flowthrottling section. Therefore, the corresponding working speed of the actuating mechanism of the main machine can be regulated by operating the multiple direction control valve. Especially during starting or stopping process, the working speed can increase or decrease gradually to overcome the shock and to ensure smooth starting or stopping.
The ZS3 series multiple directional control valves have the same oil circuit, spool valve function, and positioning and returning modes as the ZS1valves.
