Single chamber double orifice triple function air release valve combine both large and small orifices within one valve and offers solution for releasing and adding air to water pipelines, protecting pipe line systems and improving efficiency. The three function automatic air valve discharge the large volume of air during charging of the pipeline, admit air during emptying of the pipeline and discharge air accumulated under normal operating conditions. Our air valve offered with a kinetically designed large orifice and float to avoid premature closing of the valve by discharging air. The capillary tube act as a small orifice which is sealed by a float at all pressure above atmospheric except when air accumulates in the valve body. Air valves are made in ductile iron body with floats in stainless steel. Valves are suitable for clean water applications.
- Large orifice to intake high quantities of air during draining the pipeline
- Large orifice to release high volume of air during filling the pipeline
- Large orifice to release air in a controlled manner to reduce pipeline surge.
- Small orifice to release small volume of air during operation under pressure
