The needle valve actually failed at 150×

I can't understand that the initial pressure of 150× and the theoretical explosion limit pressure should be less than 110mpa, but the maximum working pressure of my needle valve reaches 400mpa. Why did it fail?

这是它的照片。在几次150次射击后,它变得无法保持密封。

Ah, but what's the maximum working temperature?

I don't know its maximum working temperature, but it is a metal hard seal, so I think the temperature should have little effect, which may be a product quality problem.

Might be due to being subjected to a shock load...
