Air release valves are a significant component in pipeline systems as they are designed to solve the issue of air pockets. They usually occur in the highest point of the pipeline system which if not managed can cause major downsides.

While there are different varieties of these valves available, a double orifice air valve seems like a favourable choice. The two orifice openings - large and small, allows for both air admission into the pipeline till it’s refilled and release air that has built up at highest points.

The simultaneous functionality makes these valves an indispensable tool for use. We at Dutco Tennant LLC supply high-quality double orifice air relief valves by AVK. The valves are designed meticulously equipped with the best features, making them an ideal choice in industrial systems.

The Unique Features of AVK Double Orifice Air Valves

 

The innovative design and robust construction of these valves makes them stand out from the rest. Let’s explore why this air valve release solution is the ideal choice for your system:

 

Comprehensive Air Management

 

The AVK double orifice air valves are designed with triple acting functionality. This allows the valve to serve three purposes:

  • Rapid Filling and Draining: They perform quick expulsion of air when the pipeline is filling or draining, preventing the formation of air pockets.
  • Continuous Air Release: During normal operation, the valve automatically discharges small quantities of air that accumulate in the system. Thus, maintaining efficient flow and pressure.

 

 

Aerokinetic Design Prevents Premature Closure

 

One of the standout features of the AVK double orifice valve is its unique 'Aerokinetic' design. Unlike conventional air valves, this design ensures that the valve remains open until all air is expelled. Here’s how it works:

The float inside the valve chamber does not close prematurely due to the rush of air. Instead, the valve closes only when all air is completely expelled and water starts entering the chamber.

This prevents false closure and ensures that the system is air-free, avoiding operational issues such as water hammer and flow disruption.

 

Large Air Flow Capacity

The valve boasts a large air flow capacity, making it highly effective in handling significant volumes of air in the system. This feature is crucial during the initial filling of the pipeline. It also helps when there is a sudden drop in pressure, as it prevents vacuum formation and potential pipeline damage.

 

Durable Construction 

Durability is a key factor in the performance of any valve, and the AVK double orifice valve excels in this regard:

All ductile iron components in contact with water are coated with GSK approved fusion bonded epoxy. The coating provides a protective barrier against corrosion and wear.

The use of WRAS approved polymer materials and stainless steel (AISI 316) for other internal parts ensures longevity. The materials in use are also resistant to harsh environmental conditions.

 

Reliable Seals 

The seals in the AVK double orifice valve are made of WRAS approved EPDM rubber. It is known for its excellent compression set and ability to regain its original shape. 

This ensures a tight seal even after repeated cycles of opening and closing, maintaining the integrity of the valve over time.

 

Compliance with Drinking Water Standards

All materials used in the construction of the AVK double orifice valve are approved for use with drinking water. This includes:

  • The fusion bonded epoxy coating on iron parts.
  • The EPDM rubber seals and ABS seat.
  • Stainless steel components that resist corrosion.

This makes the valve a safe and reliable choice for applications involving potable water systems.

 

No Contact Between Moving Parts and Internal Coating

In many valves, moving parts can scrape against internal coatings, leading to wear and potential contamination. The AVK double orifice valve is designed such that no moving parts come into contact with the internal coating. 

This not only enhances the longevity of the valve but also maintains the purity of the water passing through it.
