Ultrasonic Cleaning

MIZUP cleaning procedures are divided into the following 3 processes according to the manufacturing SOP.

• The general ball valve is cleaned with filtered water, which reduces the problem of water marks and furring on the surface after cleaning, and improves the quality of general products.
• The sanitary ball valve is cleaned with RO reverse osmosis pure water, so that the cleanliness of the sanitary ball valve exceeds the general standard.
• . Ultrapure water (conductivity 18MΩ·cm) also be used by Electronic grade products , which is equivalent to the cleaning of semiconductor fabrication plant level. After the metal center oil inspection, the residual amount is less than 0.5mg/ft².
