More than 20 manufacturers can not produce the hydraulic relief valves with wall thickness less than

Smith is from Mexico and has been smooth on purchasing hydraulic valves, but encountered a nail when purchasing a hydraulic relief valve with a wall thickness of less than 2mm. His boss received an order for a special hydraulic relief valve. The wall thickness of the valve cage of the hydraulic relief valve is less than 2mm, and the fitting clearance of the valve cage is 0.016mm-0.02mm. Thin wall and high precision.

Smith found AAK on Google and left a message asking: can AAK make samples for a hydraulic relief valve with wall thickness less than 2mm?

3 weeks later, AAK sent the hydraulic relief valves. 1 week later, Smith advised that the samples of AAK hydraulic relief valve has a wall thickness of the valve cage less than 2mm, the cylindricity was not more than 0.01mm, the roughness Ra was ≤ 0.2, and the pass rate was 100%. While the pass rate of another hydraulic valve manufacturer was 80%.
