Difference in MAW valve?

[tjrwls907]

I am planning to wear MAW's valve on the 2165 of the current melton.
Can you tell the difference between the original valve from the instrument company and the valve of MAW??
Currently I'm considering buying this.
If you know any differences, please let me know!
