This 4-section sectional (modular) directional control valve uses manual lever operation to control multiple actuators in one compact valve bank. Rated flow is 160 L/min with a maximum pressure of 350 bar, making it suitable for high-demand mobile hydraulic circuits. The integrated electric unloading function helps reduce heat generation and energy loss by unloading the pump when functions are not required, improving overall machine efficiency.
Key advantages:
- High capacity for multi-function machines: 4 spools/4 sections for steering, boom, auxiliary lines, and attachments.
- Heavy-duty pressure rating: up to 350 bar for harsh working conditions.
- Wide fluid compatibility: operating viscosity range 12–400 mm²/s supports cold start and high-temperature operation.
- All-weather performance: ambient temperature range -40°C to +80°C for outdoor equipment.
- Flexible port configurations for global builds: inlet options G1, G3/4, SAE 12; outlet options G1, SAE 16; port sizes G3/4, G1, SAE 12.
Typical applications include construction and earth-moving machinery (mini/midi excavators, backhoe loaders, wheel loaders), material handling equipment (telehandlers, forklifts), aerial platforms, agricultural tractors with loaders, and concrete boom pumps. Suitable for OEM manufacturing, customization, private labeling, and wholesale/distributor supply.
