Ductile Iron Combination Air Release Valve with Threaded And Flange Connection and Stainless Steel Float for Fluid Transport Systems

Product Description:

The Combination Air Release Valve is an essential component designed to enhance the efficiency and safety of potable water systems. Engineered with precision and built to meet rigorous standards, this valve incorporates a resilient seated seal type that ensures reliable and leak-free operation under various conditions. Its robust design is ideal for use in water distribution networks, helping to maintain system performance and protect infrastructure from air-related issues.

One of the standout features of this Combination Air Release Valve is its triple functions, which include automatic air release during the filling process, air intake during system draining, and the release of accumulated air during normal system operation. These functions work together seamlessly to prevent air pockets from forming within pipelines, which can cause flow disruptions, increased energy consumption, and potential damage to the system. By efficiently managing air within the network, the valve supports consistent water flow and reduces the risk of water hammer—a common problem in pressurized water systems.

Constructed with a stainless steel float, the valve ensures durability and corrosion resistance, making it suitable for long-term use in potable water applications. Stainless steel offers excellent strength and longevity, even in environments where the valve is exposed to varying temperatures and water chemistry. The float's responsive movement within the valve body allows for precise control of air release and intake, contributing to the valve’s high performance and reliability.

The valve is available in a wide range of sizes, from 50mm up to 300mm, allowing for versatile application across different pipeline diameters. This size range accommodates both small and large water distribution systems, making the valve adaptable for use in residential, commercial, and industrial potable water networks. Whether integrated into new installations or retrofitted into existing systems, the valve provides a dependable solution to air management challenges.

Installation flexibility is enhanced by the valve’s end connection options, which include both threaded and flange types. These connection methods facilitate easy integration with various pipeline configurations and standards, ensuring compatibility and simplifying maintenance or replacement procedures. The availability of both connection types means the valve can be tailored to specific project requirements, streamlining the installation process and reducing downtime.

Operating within a temperature range of 0°C to 80°C, the Combination Air Release Valve is suitable for most potable water applications, including those in climates with moderate temperature fluctuations. This temperature tolerance ensures that the valve maintains its sealing integrity and functional performance without degradation, even under varying operational conditions.

Manufactured to comply with the EN1074-4 standard, this valve meets stringent European quality and safety requirements for valves used in water supply systems. Adherence to EN1074-4 certification guarantees that the valve has been tested for durability, reliability, and performance, providing confidence to engineers, contractors, and end-users alike. Compliance with this standard also ensures that the valve supports sustainable water management practices and contributes to the overall safety of potable water systems.

In summary, the Combination Air Release Valve is a highly reliable, efficient, and durable solution for managing air in potable water pipelines. Its resilient seated seal type, stainless steel float, versatile end connections, and compliance with EN1074-4 make it an excellent choice for ensuring the smooth operation of water distribution networks. By performing triple functions that address air release and intake, this valve minimizes the risk of system disruptions, protects infrastructure, and helps maintain water quality. Available in sizes from 50mm to 300mm and capable of operating within a 0°C to 80°C temperature range, this valve is designed to meet the diverse needs of modern potable water systems.
