Features of the Modern R300-9 Control Valve:
1. Multi-channel Integrated Structure:
Each valve body (boom, stick, bucket, swing, travel) adopts an
integrated modular design, resulting in a compact size and
convenient installation and maintenance.
2. Load Sensing (LS) System:
Features load feedback functionality, automatically adjusting pump
flow according to load changes to reduce energy loss and improve
fuel economy.
3. Electro-proportional Control:
The electro-proportional valve (EPC valve) controls the main valve
spool opening based on electrical signals from the operating
handle, achieving precise flow control and smooth operation.
4. Excellent Coordination of Combined Actions:
Coordination between various actions is achieved through priority
valves and flow distribution logic valves, such as balancing boom
lifting and swing, and stick operation.
5. Built-in Multiple Safety Valves:
Includes a main safety valve, check valve, overload protection
valve, and anti-cavitation valve to prevent system overpressure,
backflow, and dry suction.
6. Regeneration System Design:
During the recovery operation of the boom or bucket, the energy
from the return oil is used to participate in the system's oil
supply, increasing speed and reducing fuel consumption.
