Ductile Iron Air Release Valve are designed to automatically expel trapped air pockets from pipelines during operation and filling, and to allow air intake during pipeline draining. This prevents air locking, pressure surges, and flow disruptions in water transmission, irrigation, and sewage networks. Ductile Iron Air Release Valve for clean water.
