• Sandwich structure, flexible combination on demand.
• Load pressure compensation, load pressure independent flow distribution.
• Hydraulic pilot control, electric proportional (or switch) control.
• Load holding function is available for boom and arm.
• Limit the maximum pressure of the system through the LS relief valve.
• Through the secondary relief valve to limit the execution system from overload and set the secondary pressure.
• Small pressure loss and low energy consumption.
• Precise control, stable proportional control, comfortable maneuverability.
• High repetition accuracy and small hysteresis.

Mounting and usage

1. During handling, mounting and storage, avoid striking or damaging the machined surface.
2. Do not remove the seals at each port before mounting. It is not allowed to disassemble at will in dusty places to prevent dirt from entering inside.
3. Before use, check whether the technical parameters, spool valve function and oil circuit type of sectional valve meet the requirements.
4. The mounting surface should be flat and correctly connected to each port. The tightening torque of mounting screws, joints, etc. shall meet the requirements.
