Specialityvalve is one of the top leading Double Orifice Air Release Valve Manufacturer in India. Pipeline equipment such as Double Orifice Air Release Valves is essential. When an empty line has been filled, these valves release air from the pipeline and take air into the pipeline whilst pipeline is being discharged. They also release microscopic air pockets that become trapped in the pipeline while it is under strain.


Types of Double Orifice Air Release valve:
• Double Orifice Kinetic Air Valve
• Single Orifice Air Release valve

How does a Double Orifice Air Release Valve work?

Air emission through two orifices an operator is not required for valves. After the first start-up, these valves rely on natural law for buoyancy and do not require operators. The double orifice air release valve floats at the bottom of the orifices when an empty pipeline is being filled for the first time. At this time, the valve is free to discharge air. When water arrives and fills the opening, the floats rise with it, closing snugly on the sealing rings and preventing water from escaping. The little air pockets that get caught in the pipeline are gathered in the small orifice chamber, where the float slides down a bit and lets the air out. The float securely plugs the hole with increasing water, preventing water from leaking out. When the water leaves the valve chamber and the water is discharged, the floats in the pipeline fall down, allowing air into the pipeline. This keeps the pipeline from fracturing.

Air Release Valve Manufacturer in India
Specialityvalve is a well-known Air Release Valve manufacturer in India. Air release valves aid in the ejection of trapped air, ensuring a smooth stream of water and efficient operation of pipelines. When air becomes trapped in the system, the internal lever mechanism increases the float force, which then opens the vent even more. The valve is made of corrosion-resistant mechanical parts and includes a shock-resistant inner tube.
