Wholesale IBC DN80 Integrated Butterfly Valve Manufacturer, Suppliers

The IBC DN80 Integrated Butterfly Valve is a complete, ready-to-install unit designed for 3-inch (DN80) IBC container outlets. Its integrated flange or weld-end spool allows for direct, secure mounting. The valve operates with a low-torque quarter-turn mechanism, features a full-port design for minimal flow restriction, and is rated for pressures up to PN10/16. The standard temperature range is -20°C to +150°C, depending on seal material. It includes an ISO 5211 top mount for easy attachment of manual handles or automated actuators.

The primary structure is constructed from high-grade 316/316L stainless steel, chosen for its superior corrosion resistance, especially in challenging chemical and CIP/SIP environments. The integrated spool and valve body are typically machined from solid bar stock or forgings for maximum integrity. The rotating disc is made from polished stainless steel. The sealing system utilizes a high-performance seat made from PTFE, EPDM, or FKM (Viton®), ensuring compatibility with a wide range of aggressive and sensitive media while meeting FDA and EHEDG compliance.

Manufacturing begins with the precision CNC machining of the integrated valve body and spool from stainless steel, ensuring a seamless internal flow path and perfect dimensional accuracy for mounting. The disc is contoured and polished to a mirror finish. Critical components are then assembled in a clean environment. The integrated unit is cleaned, passivated, and electro-polished to achieve a smooth, hygienic surface finish that prevents bacterial adhesion and facilitates cleaning. All assembly is performed with calibrated torque tools to ensure consistent performance.

This integrated valve is designed for applications requiring a secure, leak-proof, and compact connection directly on the IBC, reducing the need for additional pipe spools and fittings.

Each integrated valve undergoes a rigorous multi-stage inspection. Dimensional checks verify the spool and flange/weld-end compatibility. Surface finish is measured to ensure it meets sanitary specifications. Every unit is subjected to a 100% pressure test, including both a shell strength test and a seat leakage test per ISO 5208 standards, to guarantee zero leakage at 1.5 times the rated working pressure. A final operational test confirms smooth, friction-free rotation of the disc.

To protect the precision-machined surfaces and integrated assembly, the valve is thoroughly cleaned and all ports are sealed with protective plastic caps. It is then wrapped in VCI (Vapor Corrosion Inhibitor) paper to prevent corrosion and placed in a sealed plastic bag. The unit is securely packed in a custom-fitted, foam-lined corrugated carton to prevent any movement or impact damage during transit. Packaging is clearly labeled with part numbers, material certifications, and inspection status.
