About this product

This Dual Check Valve, WATERMARK Approved, is a critical component designed to prevent backflow and contamination in water systems, ensuring the integrity of potable water supplies. Its primary function is to allow water to flow in one direction while automatically shutting off flow in the opposite direction, safeguarding against the mixing of potable water with non-potable sources. Key features include robust construction and reliable sealing mechanisms, engineered for consistent performance and longevity. The valve's threads conform to ISO228 standards, which are internationally recognized and equivalent to DIN 259 and BS2779, ensuring broad compatibility with existing plumbing infrastructure. Constructed from high-quality, durable materials chosen for their resistance to corrosion and water damage, this valve offers exceptional build quality and a reliable finish suitable for demanding environments. While specific size ranges and customisation options are not detailed, the adherence to international thread standards suggests a range of common sizes will be available to suit various applications. Typical applications include residential, commercial, and industrial plumbing systems, particularly where cross-contamination is a concern, such as in irrigation systems, heating circuits, and backflow prevention assemblies. This product is ideal for importers, wholesalers, and retailers seeking reliable plumbing hardware, as well as end-users in construction and maintenance industries. Its WATERMARK approval signifies compliance with Australian plumbing regulations, a globally respected standard, making it an excellent choice for international trade buyers prioritizing quality, safety, and regulatory compliance.
