A Double Air Valve combines the functions of both air release and air/vacuum valves in a single unit. It is designed to automatically release small pockets of trapped air during normal pipeline operation and to allow large volumes of air to enter or exit the pipeline during filling or draining. This dual functionality helps to protect the pipeline from pressure surges, vacuum conditions, and potential damage. Shanay Traders manufactures and supplies high-performance Double Air Valves, ensuring effective air management in fluid systems for optimal operation and longevity.
