Tractor steering valve


Tractor steering valve is a key component in the tractor hydraulic steering system, which is responsible for controlling the hydraulic oil flow direction of the steering cylinder, so as to realize the steering function of the tractor. The correct operation of the steering valve is critical to the stability and operational performance of the tractor.


A tractor steering valve is usually composed of a valve body, a spool, a spring, a control handle, and other parts. The valve body is equipped with an oil inlet, an oil return port and an oil circuit leading to the steering cylinder. The spool moves inside the valve body to control the flow direction of the hydraulic oil by changing the opening and closing state of the oil channel. Springs are used to hold the spool in a stationary position. The control handle is attached to the spool, and the driver controls the steering by operating the control handle to move the spool.


During the steering of the tractor, the driver operates the control handle so that the valve core moves in the valve body. When the valve core moves to a certain position, the oil inlet is connected with the oil circuit leading to the steering cylinder, and the hydraulic oil enters one side of the steering cylinder, pushing the cylinder piston to move, so as to achieve steering. At the same time, the hydraulic oil on the other side flows back to the oil tank through the oil return port, completing the whole steering process.


In order to ensure the proper functioning of the Tractor Steering Valve, regular maintenance and inspections are required. This includes the following:

1. Cleaning: Regularly clean the Tractor Steering Valve and its surroundings to avoid dust and debris from entering the valve.

2. Check the seals: Check the seals of the tractor steering valve, such as O-rings, oil seals, etc., to make sure they are not worn or aged. If it is damaged, it should be replaced in time.

3. Check the oil circuit and joints: Check the oil circuits and joints connected to the Tractor Steering Valve to make sure they are not leaking or loose. If there is a leak, it should be repaired or replaced in time.

4. Check the spool and spring: check whether the spool and spring are worn or deformed. If necessary, it should be replaced in time.

5. Adjust the clearance: Adjust the clearance between the valve core and the valve seat appropriately according to the use and manufacturer's recommendation to ensure the flexibility and tightness of the tractor steering valve.

6. Replace the hydraulic oil: according to the manufacturer's recommendation, replace the hydraulic oil regularly to ensure the cleanliness and performance of the hydraulic oil.


The Tractor Steering Valve is the core component of the tractor's hydraulic steering system, and its proper operation is essential for the operational performance and safety of the tractor. Therefore, the driver should carry out regular maintenance and inspection to ensure that the steering valve is in good condition. At the same time, attention should also be paid to the operation specifications during operation to avoid damage to the steering valve caused by excessive operation or improper operation.
