A U-type butterfly valve (also known as a U-section butterfly valve) is designed with a specialized U-shaped seat that provides a flush transition with the body bore. When the valve opens, the disc rotates away, and the U-shaped seat resets smoothly, minimizing dead pockets where media can accumulate. This structural design ensures a clean flow path, making it suitable for systems requiring frequent flushing or the handling of viscous fluids.
This model features a ductile iron (DI) body for excellent structural rigidity, a stainless steel disc for corrosion resistance and hygiene, and a worm gear operator for smooth, self-locking manual control.
As a direct OEM/ODM manufacturer with over 19 years of export experience, Tianjin Worlds Valve Co., Ltd. builds valves to your exact specifications. Our facility is ISO 9001:2015 certified by LRQA, and our pressure equipment holds CE/PED (Module H) and UKCA certifications.

1. U-Type Seat Design–Minimized Dead Pockets
Flush Flow Path–The U-shaped seat design ensures a smooth, continuous bore when the valve is open, minimizing the crevices found in traditional seat designs.
Prevents Media Accumulation–By eliminating dead pockets where media can get trapped, the valve helps prevent bacterial growth and cross-contamination.
Handles Viscous Media–The unobstructed flow path prevents blockages when handling thick fluids, slurries, or powders.
2. Body Material–Ductile Iron (DI)
High Mechanical Strength–Ductile iron provides excellent pressure resistance and impact toughness, ensuring the valve body will not crack under pressure surges or pipeline stress.
Cost-Effective–Offers a durable and economical alternative to cast steel or full stainless steel bodies.
External Protection–The standard epoxy coating protects the exterior against atmospheric corrosion in harsh environments.
3. Disc Material–Stainless Steel
Corrosion Resistance–The stainless steel disc (CF8) resists oxidation and chemical attack from the process media.
Hygienic & Non-Toxic–Suitable for sanitary applications in food, beverage, and pharmaceutical processing.
High Durability–Maintains its mechanical integrity and smooth surface even after thousands of cycles.
4. Worm Gear Operator–Reliable Manual Control
Self-Locking Mechanism–The gearbox prevents the disc from slipping under high flow velocity, holding the valve securely at any opening angle.
Reduced Operating Torque–The gear ratio significantly reduces the manual effort required to open or close the valve.
Clear Position Indicator–A built-in visual indicator allows operators to check the valve status at a glance.
Industry | Application |
Food & Beverage | Juice, dairy, syrup lines, and CIP cleaning systems where hygiene is important |
Pharmaceutical | High-purity water and process media where residue accumulation must be minimized |
Chemical Processing | Viscous fluids and mild corrosive media (when paired with the appropriate seat material) |
Wastewater & Sludge | Lines with high solid content where standard valve cavities might clog |
Pulp & Paper | Handling pulp stock and paper coatings without trapping fibers |
