Valve Assembly Requirements

Cleaned parts must be kept sealed for installation.

The requirements for the installation process are as follows:

1. The installation workshop must be kept clean, or a temporary clean area should be built, such as using newly purchased color strips or plastic films to prevent dust from entering during the installation process.

2. Assembly workers must wear clean cotton work clothes, cotton caps, no hair leakage, clean shoes, plastic gloves, and degreased hands.

3. Assembly tools must be degreased and cleaned before assembly to ensure cleanliness.
