20 – 60 ton Excavator

We provide both positive flow control (PFC) and negative flow control (NFC) system for middle and large excavator(20~60ton) application.
Utilizing Hengli’s pump and mobile valve, the superior controllability and the fuel saving can be achieved.

The NFC system uses a measuring orifice in the bypass oil flow to generate a pressure signal, which influences the swash angle of the regulating pump.
In PFC systems the control signal is used to control both valve and pump. A complex evaluation control consisting of valve cascades in combination with software determines a certain swash angle for the pump.

Hengli has rich experience in both control systems, can provide you full qualified hydraulic solutions to save your time.
