Valve degreasing treatment method (two)

Cleaned parts must be kept sealed for installation. The requirements for the installation process are as follows:

1. The installation workshop must be clean, or set up a temporary clean area, such as using newly purchased colored cloth or plastic film, to prevent dust from entering during the installation process.

2. Assemblers must wear clean pure cotton work clothes, wear pure cotton singing on their heads, keep their hair from leaking out, wear clean shoes on their feet, carry plastic gloves on their hands, degrease and dry.
