Single Orifice Air Valve

Single Orifice Air Valve

The Single Orifice Air Valve from Solid, made from high-quality ductile iron, is engineered to continuously release accumulated air during system operation.

When air enters the valve from the pipeline, it displaces water, causing the float to drop. This allows the trapped air to escape through a small orifice, maintaining efficient system performance. 

Once the air is vented, it is naturally replaced, ensuring a seamless operation.

Designed for applications such as air compressors, pneumatic systems, and gas pipelines, this valve offers precise airflow control and can withstand pressures of up to 16 bar.

Its durable ductile iron construction guarantees long-lasting performance, while the compact, low-profile design allows for easy installation and minimal maintenance requirements.

The Single Orifice Air Valve utilizes a unique design to ensure precise and efficient airflow control. Its conical valve seat and tightly fitted plunger allow for an accurate and consistent flow of air or gas. This means you can count on it to deliver consistent performance and maintain a stable flow rate, even under demanding conditions.

The valve is also compatible with a wide range of gases and liquids, making it a versatile choice for a variety of applications. It is easy to install and maintain, with a simple design that requires minimal upkeep and repair. And thanks to its durable construction and reliable performance, it delivers long-lasting value and reliability.

So if you are in need of a reliable air valve for your industrial processes, choose the Single Orifice Air Valve. With its precision control and durable construction, it is the perfect solution for your valve needs.

This air vent is usually mounted at outlet side of  pump or water distribution pipeline. It performs to release the air collected inside so as to improve the working capacity of pump station and pipeline. When the pipeline is under negative pressure, the plug will  open rapidly to fill in air to protect pipeline from negative pressure damage.

Note: This model can not be used in sewage pipeline.

Features:

1, Reliable Sealing with special design
2, Automatic air releasing and filling without manual operation
3, Dependable performance and long service life
   Float ball moves in fixed routine without hitting the shell
4, Short in height than other same kind air vents

Three functions: 
1, large amount of air releasing (main vent )
2, small amount of air releasing (small vent overriding)
3, rapid air filling 

It allows air to escape when filling the pipe.
It allows air to enter when emptying the pipe (preventing pipe collapse)
It allows continuous automatic control, eliminating accumulated air, even when the system is under pressure.
