Option for positive flow control system and negative flow control system

— Main Function Pump:

Double pump, compact structure design, easy to control, can be directly installed with flange, saving space, and the complete set of components can also save debugging time; according to the characteristics of different machine models, supply different types of systems; the products are all lightweight design, making the machine more compact;

— Main Control Valve:

The main control valve integrates a swing priority valve, a straight travel valve, a flow regeneration valve, etc., and the valve body is also designed as mono block type, which reduces the pressure loss of the flow passage and realizes more energy-saving;

— Swing:

Built-in mechanical brake, relief valve, charge valve, anti-reverse valve; two-way rotation, the mounting flange can be directly connected to the gear ring of the reducer; based on mature technology, conducts lightweight, compact and improvement and increase the output power.
