In an effort to ensure proper cleaning procedures are performed on valves intended for oxygen service, Watson Valve Services has upgraded its existing clean room within its manufacturing plant in Houston.
Watson Valve Services’ clean room is operated by trained technicians and is constructed with positive pressure ventilation which is used to limit airborne particles and environmental contamination. Both mechanical and solvent cleaning methods are used. Watson Valve maintains separate tools, benches and equipment to reduce the potential for cross contamination. Strict procedures are used to maintain and keep all O2 clean room equipment clean and free of contaminants. The equipment and tools are periodically programmed to be cleaned to remove any possible contamination.
After each valve is thoroughly cleaned and re-assembled, it is given a seat and shell test which ensures sealing capability is maintained. Once inspected, all cleaned Watson valves are carefully labeled and sealed to protect the cleaned valve during storage and shipment.
