In order to ensure proper cleaning procedures are performed on valves intended for oxygen, ozone, chlorine, hydrogen peroxide, isocyanate and other applications, DeZURIK has constructed a new dedicated clean room within its Sartell manufacturing plant in Minnesota.
Operated by trained cleaning technicians, DeZURIK’s clean room is constructed with positive pressure ventilation to limit environmental contamination and airborne particles. The facility maintains all separate tools, benches and equipment to reduce the potential for cross contamination. Cleaning procedures include mechanical, ultrasonic and/or solvent cleaning methods, with each part inspected under both white light and UV Black Light to identify any contaminants.
After each valve is thoroughly cleaned and re-assembled, it is given a second seat and shell test to ensure sealing capability is maintained. Once inspected, all cleaned DeZURIK valves are carefully labeled and specially sealed to protect the cleaned valve during shipment and storage.
