Product Features
- Overlay valve
- Porting pattern in accordance with DIN 24340A and ISO 4401
- Used to limit the main oil flow or pilot oil flow of 2 actuator oil ports
The Z2FS superimposed one-way throttle valve adjusts the oil flow rate by changing the cross-section size of the throttle port to achieve flow control. In the reverse direction, the oil flow returns directly through the one-way valve. For the 10-diameter, different installation positions can be selected to achieve inlet throttling or outlet throttling. For the 16 and 22-diameter, different models can be selected to achieve inlet throttling or outlet throttling, and the two oil circuits of the working oil chamber can be connected at the same time.
