Excavator Distribution Valve Standby Valve

PC200/300/400 Spare Valve standby hydrulic control valve Installation Instruction
1 The pipeline must use pickling phosphating tube to prevent valve core sticking to damage valve rod.

2.The aluminum cover of jint is M14*1.5,power slightly to prevent falling off due to tight-ening.
3.Because the gap of valve rod and valve body is small it ill get stuck valve rod if you use too much force to tighten the screw.If the valve core is stuck,just please loosen four screws.
4.PC200/300 spare valve is reverse thrust,so the oil inlet of pilot valve is in thehydraulic tank level,the mainoil low is in the driving cab level.
Noted:Installation Location of Sensor
PC200-6/-7 excavator:Install below empty filter which have a line and have sensor plug.Using sensor"T"to connect sensor,oil iniet guide tube of pedal valve and oil inlet guide tube of spare valve.(Prepare one piece of 1.5 meter tube of spare valve by yourself).The sensor of 30Ton excavator located in the gap of excavator frame and cab sde.
PC-8 excavator:using sensor "T"insalled on port A of pedal valve.
5.Above 30T excavator, we advise that the oil return to radiator not to valve and oil tank.

Excavator Distribution Valve

The excavator distribution valve is a critical component in the hydraulic system of an excavator. It is responsible for distributing hydraulic fluid to various actuators (such as the boom, arm, bucket, and swing motor) according to the operator's control inputs.

Key Functions:

  1. Fluid Distribution:

      • The distribution valve directs hydraulic fluid from the pump to the appropriate actuators, allowing the operator to control the movement of the excavator's boom, arm, bucket, and swing.

      • It ensures that hydraulic pressure and flow are delivered to the actuators in a controlled manner, enabling precise and efficient operation.

  2. Flow Control:

      • The valve regulates the flow of hydraulic fluid to the actuators, which helps to control the speed and force of the excavator's movements.

      • This allows the operator to adjust the excavator's performance based on the specific task requirements.

  3. Pressure Relief:

      • The distribution valve incorporates pressure relief valves that protect the hydraulic system from overpressure.

      • If the hydraulic pressure exceeds a predetermined limit, the relief valves open, allowing excess fluid to flow back to the tank and preventing damage to the system components.

Types:

There are several types of excavator distribution valves, including manual, hydraulic, and electronic control valves. Each type has its own advantages and is suited for different applications.

  • Manual Control Valves:

      • Operated by the operator using levers or pedals.

      • Simple and reliable, but may require more effort from the operator.

  • Hydraulic Control Valves:

      • Use hydraulic pressure to control the valve's operation.

      • Offer smoother and more precise control than manual valves.

  • Electronic Control Valves:

      • Utilize electronic signals to control the valve's operation.

      • Provide the highest level of control precision and can be integrated with advanced control systems.
