Message: | Peter is from Australia. One of his old customers wanted to purchase a special hydraulic flow control valve. Peter realized that the valve hole of this hydraulic flow control valve has high accuracy and is difficult to process. If the surface roughness and cylindricity error cannot be well controlled, it is easy to cause the valve spool to be stuck. As expected, he contacted more than 20 hydraulic flow control valve manufacturers in 3 days, but none of them was confident. The customer has urged the quotation twice, and now even the manufacturer can't be determined. Peter was very worried. |
