Wholesale China IBC DN50 Welded Butterfly Valve - Durable, Sanitary Valve from Trusted Suppliers & Factory for Liquid Transfer Manufacturers, Suppliers
Product Description
Product Parameters
Our IBC butterfly valve is designed to meet industry standards for IBC container connections. Key specifications include a standard 2-inch nominal bore size, compatible with DN50 flanges. It operates within a temperature range of -10°C to +120°C and can handle pressures up to 10 bar. The valve features a 304 or 316 stainless steel shaft and disc, with EPDM or PTFE seals for versatile chemical compatibility. The ergonomic manual handle provides a quarter-turn operation for quick open/close functionality.
Production Raw Materials
We prioritize hygiene and durability. The valve body is typically crafted from high-flow, corrosion-resistant polymers like polypropylene (PP) or conductive polyethylene. All wetted parts in contact with media are made from FDA-compliant or EC1935/2004-certified materials. The core sealing components utilize premium EPDM, FKM (Viton), or PTFE, selected for their resilience against aggressive substances. Metal components are precision-machined from high-tensile strength stainless steel.
Production Process
Manufacturing begins with the injection molding of polymer components under controlled conditions to ensure dimensional accuracy and material integrity. Metal parts are CNC-machined and polished to a sanitary finish. Critical components like the disc and shaft are assembled with precision to guarantee perfect alignment. The valve is then assembled in a clean environment, with each unit undergoing rigorous function and seal testing before final inspection and packaging.
Usage Scenarios
This valve is essential for the controlled discharge of liquids from IBC totes. Its primary applications include:
- Chemical Industry: Transferring solvents, additives, and process liquids.
- Pharmaceutical & Cosmetics: Handling purified water, raw ingredients, and intermediate products under hygienic conditions.
- Food & Beverage: Managing edible oils, syrups, juices, and dairy products.
- Water Treatment: Dosing of treatment chemicals.
Quality Inspection
Every valve is subject to a multi-stage quality assurance protocol. This includes dimensional checks, visual inspection for defects, and material certification review. Each unit undergoes a critical air-under-water pressure test to verify leak-tight integrity at specified pressures. Operational tests ensure smooth 90-degree rotation without binding. Samples from production batches undergo periodic destructive testing and chemical resistance validation.
Packaging & Shipping
Valves are individually packaged in sealed plastic bags to prevent contamination during transit and storage. They are then placed in sturdy cardboard boxes with protective inserts to prevent damage. Packaging clearly displays the product code, material specifications, and batch number for traceability. We offer bulk packaging options for large orders and ensure compliance with all standard freight requirements for safe and efficient delivery worldwide.
After-Sales Service
We stand behind the quality of our products with a comprehensive warranty against manufacturing defects. Our customer support team provides technical assistance for product selection, installation guidance, and troubleshooting. We maintain an inventory of common spare parts like seal kits for quick dispatch. Our service commitment ensures reliable performance and minimal downtime for our clients' operations.
