Number of Ports: The main control valve for the 349GC excavator usually features a comprehensive set of ports. Typically, it may have around 14 to 18 ports. These include inlet ports for receiving pressurized hydraulic fluid from the pump, multiple outlet ports for directing fluid to different actuators, and return ports for sending the used fluid back to the hydraulic tank.
Port Sizes:
Inlet ports are designed to handle the high flow rate from the hydraulic pump, with diameters typically ranging from 16 mm to 22 mm. This allows for efficient intake of the pressurized fluid.
Outlet ports connected to individual actuators are sized according to the specific flow and pressure requirements of those components. Common diameters for these ports can range from 10 mm to 18 mm, ensuring proper fluid delivery to each actuator.
