Spray rinse and steam injection valves are used to clean or heat batch polymerization (PVC, Latex and Polyurethane) reactors. Developed together with leading PVC producers the SchuF Type 27SR, ensures a unique two stage efficient spray pattern, while maintaining a simple, rugged design, utilizing the famous SchuF metal-to-metal shut-off, first developed in the 1920’s. Protect the environment by minimizing and efficiently directing the use of water, steam, solvents and anti-sticking agents. Used to clean reactors after each batch operation by spraying the interior of the vessel with cleaning agents in the polymer and pharmaceutical industry, especially in the production of PVC.
