Applications

The load-sensing control block is ideal for combine harvesters, precision seeders, tractors, and smart irrigation systems, addressing common limitations of traditional valves with advanced CAN bus load-sensing solutions:

Applications

Issues with Traditional Valve

CAN Bus Load-Sensing Solution

Combine harvester

Header lifting is unstable, causing high crop loss rates

Electro-proportional fine adjustment with pressure compensation keeps header height steady

Precision seeder

Inconsistent seeding depth leads to uneven germination

Closed-loop hydraulic cylinder pressure control ensures uniform downforce across all planting rows

Large tractor hitch system

Power is unevenly distributed when operating multiple implements simultaneously

CAN bus coordination manages multi-valve flow, synchronizing deep tillage plows and fertilizer spreaders

Smart irrigation equipment

Unable to adjust water output dynamically based on soil conditions

Using GIS data and CAN bus signals, valve opening is automatically adjusted for optimized irrigation
