Valve Body

The main function of the valve block

1. Oil channel: there is a complex oil circuit processed inside the valve block, which is used to connect the oil inlet, the oil return port and the actuator oil port.

2. Component installation: The valve block provides space and interfaces for installing components such as the spool, valve sleeve, spring, and electromagnetic coil.

3. Sealing effect: Through the seal (such as O-ring) to ensure that the hydraulic oil will not leak.

4. Support and fixing: Provide precise support for the spool and valve sleeve to ensure the stability and accuracy of its movement.

5. Transfer liquid pressure: Transfer the pressure of hydraulic oil to the spool to drive its movement.

Production of valve block

1. Material selection:

- Valve blocks are usually made of high strength aluminum alloy, stainless steel or cast iron.

- The material should be resistant to corrosion and high pressure, and have good processing properties.

2. Machining accuracy:

- The machining accuracy of CNC Machined Valve Body Parts directly affects the performance of the servo valve, especially the dimensional accuracy of the oil circuit and mounting holes.

- High precision machining equipment (such as CNC machine tools) is the key to manufacturing valve blocks.

3. Mechanical processing:

- Use CNC machine tools for precision machining of Non-standard valve manifolds, including drilling, milling, grinding, etc.

- Dimensional tolerances and surface roughness should be strictly controlled during machining.

4. Cleaning and testing:

- After processing, Specialized miniature valve blocks should be thoroughly cleaned to remove cutting chips and oil.

- Check the size and shape of the valve block by means of inspection equipment (e.g. coordinate measuring instrument).
