Hydraulic throttle valve is designed for the hydraulic system that requires different flow rate while a hydraulic system in operation. Finotek hydraulic throttle valve Z2FS is easy to control system flow rate while adjusting hexagon socket, especially the hydraulic system is working, the adjustment of our valves is not much heavy.

Z2FS Hydraulic throttle valve is often installed in middle of the WH hydraulic control valve and WE solenoid valve, to control the inlet and outlet flow, or end of pipeline in the modeling machines to establish and control back pressure of the system. It is not effective if the back pressure is too large, it will lead to loss the hydraulic power and reduce system efficiency.
