Gear Operated U Type Flange Butterfly Valve with Nylon Coated Disc
Tianjin Worlds Valve Co., Ltd. – Engineered for Efficient Flow and Durable Performance
CBF02-TU03-Operation and Maintenance Manual DOWNLOAD
1. Hydrodynamic U-Type Disc for Maximum Flow Efficiency
Reduced Energy Consumption: The patented U-shape (or double-offset) disc profile is engineered to streamline fluid flow, reducing turbulence and pressure drop by up to 25% compared to conventional disc designs. This translates directly into lower pumping energy costs over the valve's lifetime.
Cavitation & Water Hammer Mitigation: The optimized disc geometry promotes smoother flow, minimizing the risk of cavitation damage and pressure surges in the piping system.
2. Protective Nylon 11 Disc Coating for Enhanced Durability
Corrosion & Abrasion Defense: The ductile iron disc is coated with a resilient, thermally bonded layer of Nylon 11 (Polyamide 11). This creates a tough, chemically inert barrier that protects against rust, scaling, and wear from particulates in water and mild chemical services.
Non-Stick Surface & Easy Cleaning: The smooth Nylon surface resists scaling and biological fouling, prevents particle adhesion, and simplifies maintenance cleaning procedures.
3. Precision Worm Gear Operation for Effortless Control
High Mechanical Advantage: The heavy-duty worm gear operator provides significant torque multiplication, allowing for easy opening and closing of the valve even against higher differential pressures with minimal handwheel effort.
Accurate Positioning & Stability: The self-locking gear mechanism enables precise flow modulation and securely holds the disc in any set position (from 0 to 90 degrees) without creeping.
4. Robust Flanged Body for a Secure, Leak-Free Connection
Reliable Pipeline Integration: The flanged ends (compliant with ANSI B16.5 or EN 1092-1 standards) ensure a strong, bolt-to-bolt connection that is ideal for mainline services, handling system stress effectively, and facilitating easier gasket alignment for a bubble-tight seal.
High-Pressure Integrity: The flanged design provides superior structural strength suitable for PN16/PN25 pressure classes.

Energy-Saving Design: U-type disc directly reduces system operating costs by minimizing pump head loss.
Long-Term Corrosion Protection: Nylon 11 coating extends disc and valve life in corrosive or scaling water conditions at a fraction of the cost of stainless steel.
Superior Manual Control: The gear operator ensures easy, precise, and stable valve positioning for all operators.
Robust & Leak-Resistant Connection: The flanged body offers the most reliable and serviceable connection for critical applications.
Certified Quality & Custom Support: Backed by international certifications and available for OEM customization including specific gear ratios, coating colors, and flange standards.
This valve is engineered for systems where flow efficiency, durability, and reliable manual control are critical:
Water & Wastewater Treatment Plants: Pump discharge, filtration inlet/outlet, and main distribution lines.
HVAC Systems: Primary & secondary chilled/heating water circuits, energy transfer stations, and cooling towers.
Industrial Cooling & Process Water: Large-scale cooling water networks, heat exchanger supply.
Irrigation & Water Supply: Pump station discharge and main transmission pipelines.
General Industrial Services: Where energy savings and low maintenance are prioritized.
This butterfly valve features a hydrodynamic U-shaped disc made of ductile iron with a protective Nylon 11 coating. This combination delivers the strength and cost-effectiveness of ductile iron along with enhanced corrosion and abrasion resistance, offering a reliable and economical flow control solution for water treatment, HVAC, and general industrial systems.
