Double Orifice Air Release Valve Manufacturer in India

Specialityvalve is the leading Double Orifice Air Release Valve Manufacturer in India. A Double Orifice Air Release Valve is a specialized type of valve used in pipelines and water distribution systems to automatically release air trapped inside the system. Unlike regular air release valves that have only one opening for releasing air, this valve has two separate openings or orifices. This design allows it to efficiently release large volumes of air and prevent the formation of air pockets or bubbles, which can obstruct the proper flow and operation of the fluid inside the pipeline. The second orifice in the valve acts as a vacuum breaker. It prevents the formation of a vacuum or negative pressure within the pipeline when water or fluid is rapidly drawn from it. Negative pressure can lead to pipe collapse or contamination, so the vacuum breaker function helps ensure the system operates safely and avoids damage.

Essentially, it helps maintain the system’s efficiency and ensures a consistent flow of liquid by expelling unwanted air.
