Double Orifice Air Release Valve

Speciality valve is the leading Double Orifice Air Release Valve Manufacturer in India. A double orifice valve has one large outlet and one small outlet. The large outlet admits air in large quantities while a pipe section is being drained. It is also responsible for let out the air during the pipe filing operation. The small way out is responsible for let out a small amount of accumulated air during the pipeline’s operation.

We can choose the air release valve by selecting the water distribution and sewage systems. Air valves play vital roles in sewage networks. The amount of air mount in wastewater systems is far greater than that in water passing on networks. If air valves are not present on the pipes, the confine air can significantly increase the energy needed to run the sewage network.

In addition, one of the major gases that evolved in wastewater systems and it is highly corrosive. It can attack and weaken pipes if it is not properly vented out to the atmosphere.
