Ductile Iron Combination Air Release Valve with Stainless Steel Float and Resilient Seated Seal for Fluid Systems

Product Description:

The Combination Air Release Valve is a highly efficient and reliable solution designed to enhance the performance and safety of fluid handling systems. Engineered to meet stringent industry standards, this valve is ideal for applications requiring both air release and vacuum breaking functionalities. Built with a resilient seated seal, the valve ensures superior sealing performance, preventing leakage and maintaining system integrity under various operating conditions.

One of the standout features of this Combination Air Release Valve is its robust pressure rating, available in PN10, PN16, and PN25 options. This wide range of pressure ratings allows the valve to be used confidently in systems operating under different pressure requirements, from moderate to relatively high pressures. Whether it is for municipal water supply networks, irrigation systems, or industrial fluid systems, the valve delivers consistent and dependable performance.

The valve is designed with versatility in mind, offering multiple connection types to accommodate different installation needs. It comes with both threaded and flange connection options, making it compatible with a variety of piping systems. The threaded connection provides ease of installation and maintenance for smaller pipeline sizes, while the flange connection ensures a secure and stable fit for larger diameter pipes, ranging from 50mm up to 300mm in size. This broad size availability makes the Combination Air Release Valve suitable for many different applications and pipeline configurations.

Incorporating the latest Aero Kinetic technology, this valve effectively manages the release of trapped air within pipelines, which is crucial for maintaining system efficiency and preventing issues such as water hammer and flow obstruction. The valve’s combination function means it can automatically release accumulated air during normal operation and simultaneously act as a vacuum breaker when negative pressure conditions occur. This dual function protects pipelines from potential damage caused by vacuum conditions, such as pipe collapse or joint failure.

Manufactured in compliance with EN1074-4 standards, the Combination Air Release Valve guarantees high-quality construction and performance reliability. EN1074-4 compliance ensures that the valve meets European norms for performance, safety, and durability, providing confidence to engineers and operators in its application. The resilient seated seal type used in the valve enhances its sealing capability, allowing it to withstand repeated cycles of operation without degradation or leakage. This seal type is particularly beneficial in maintaining airtight closure during vacuum conditions, further solidifying the valve’s role as an effective vacuum breaker.

Maintenance and operational efficiency are key considerations in the design of this valve. The resilient seated combination air release valve requires minimal maintenance due to its durable construction and reliable sealing mechanism. Its design minimizes the risk of clogging and operational failure, ensuring long service life and reduced downtime. Additionally, the valve’s capability to handle both air release and vacuum breaking in a single unit reduces the need for multiple devices, simplifying system design and lowering installation costs.

In summary, the Combination Air Release Valve with pressure ratings of PN10, PN16, and PN25, available in sizes from 50mm to 300mm, and featuring both threaded and flange connections, is a versatile and essential component for modern pipeline systems. Its resilient seated seal, compliance with EN1074-4 standards, and incorporation of Aero Kinetic technology make it an outstanding choice for preventing air accumulation and protecting pipelines from vacuum damage. This valve not only enhances the operational efficiency of fluid systems but also ensures their longevity and safety, making it an indispensable asset in water distribution and industrial fluid management applications.
