Full Range FBE Coated Valves: ISO 21809 Compliant Anti-Corrosion Solutions by J-VALVES

Fusion Bonded Epoxy (FBE) coating has become the mainstream anti-corrosion solution for industrial valves worldwide, widely used in gate valves, ball valves, butterfly valves, check valves, and other full-category valve products. All J-VALVES FBE series valves are designed, produced, and inspected in strict accordance with the full set of ISO 21809 series international standards, including ISO 21809-1 for single-layer FBE coating design and production, ISO 21809-2 for dual-layer FBE anti-impact coating specifications, and ISO 21809-3 for field joint coating construction standards. These standardized processes provide long-life anti-corrosion protection for buried, underwater, high-salt, and strong acid-base harsh working conditions in oil, gas, and water pipeline systems.

FBE coating is a thermosetting epoxy anti-corrosion process with superior comprehensive performance compared with traditional paint coatings. Under standard process specifications, the epoxy powder is electrostatically adsorbed on the pretreated metal substrate and cured at high temperature to form a seamless, dense, and high-adhesion protective film. Complying with AWWA C213 drinking water safety standards, J-VALVES FBE valves are non-toxic and environmentally friendly, suitable for potable water pipeline projects, while maintaining excellent resistance to salt spray, chemical corrosion, and microbial corrosion.

J-VALVES full-range FBE coated valve product line covers all mainstream industrial valve types: FBE gate valves for main buried pipeline cut-off, FBE ball valves for high-pressure corrosion-resistant switching, FBE butterfly valves for large-diameter municipal water systems, and FBE check valves for pipeline backflow prevention. All products adopt unified ISO 21809 series standard production specifications, with standardized coating thickness, surface treatment, and testing procedures, realizing consistent quality of full-series products.

In terms of quality control, all J-VALVES FBE valves implement the mandatory dual-inspection system of 100% coating thickness measurement + 100% high-voltage spark test. Relying on standardized process control and strict international standard verification, the product effectively avoids common industry problems such as uneven coating, easy peeling, and hidden pinhole defects. It has stable performance in global complex working conditions, with a design service life of more than 25 years, helping customers reduce later maintenance costs and pipeline operation risks.
