Worm Gear Lug Butterfly Valve with Nylon Covered DI Disc
Tianjin Worlds Valve Co., Ltd. – Your Reliable Source for Durable, Cost-Effective Flow Control
CBF02-TL03-Operation and Maintenance Manual DOWNLOAD
1. Precision Worm Gear Operation for Effortless Control
Smooth & Easy Manual Actuation: The heavy-duty worm gear mechanism provides a high mechanical advantage, reducing the operating torque required by up to 60% compared to standard hand levers, allowing for smooth and controlled valve operation even under higher pressure.
Stable Position Locking: The self-locking nature of the worm gear ensures the valve disc remains securely in any set position (open, closed, or partially open) without drifting, providing precise flow regulation.
Durable & Protected Gearbox: The gear operator is housed in a sealed, corrosion-resistant enclosure, protecting internal components from harsh environmental conditions.
2. Nylon 11-Coated Ductile Iron Disc for Superior Protection
Excellent Corrosion & Abrasion Resistance: The disc is coated with a thermally bonded layer of Nylon 11 (Polyamide 11), creating a tough, non-stick barrier. This protects the underlying ductile iron from rust, scaling, and damage from mildly corrosive fluids and abrasive particles.
Reduced Maintenance & Extended Life: The inert Nylon coating prevents material buildup on the disc, minimizes wear against the seat, and significantly extends the service life of the valve in demanding water and industrial applications.
Cost-Effective Alternative: Offers a more economical yet highly durable solution compared to full stainless steel construction for compatible services.
3. Lug-Type Body for Secure and Flexible Installation
End-of-Line Service Capable: The threaded lug holes allow the valve to be bolted directly to a single pipeline flange, making it ideal for isolating sections of a system or for use at the end of a pipe run.
Robust & Leak-Free Connection: Provides a strong, secure mount that withstands pipeline stress and vibration better than wafer-style valves in certain applications.
Easy Mounting & Removal: Simplifies installation and maintenance procedures without requiring special nuts or additional hardware on one side.
4. Reliable EPDM Sealing & Bubble-Tight Performance
Zero-Leakage Shutoff: Features a resilient EPDM seat that ensures excellent, bubble-tight sealing (tested to EN 12266-1 Class A standards) against water and a wide range of neutral media.
Temperature Resilience: The EPDM seat maintains sealing integrity across a temperature range of -20°C to 120°C.

Direct OEM Value: We offer competitive pricing, reliable lead times, and flexibility for custom branding or minor modifications.
Compliant & Certified: Manufactured under an ISO 9001 quality system and compliant with key international directives (CE, UKCA).
This valve is the workhorse solution for numerous industries requiring reliable and maintainable isolation:
Water & Wastewater Treatment: Pump isolation, filtration systems, general water distribution.
HVAC & Building Services: Chilled water, cooling towers, heating systems, and air handling units.
General Industrial Plant: Cooling water lines, compressed air systems, process water, and utility services.
Irrigation & Agriculture: Mainline and zone control for field and landscape irrigation.
Fire Protection Systems: Sprinkler line isolation (where specification permits).
Combining ductile iron reliability with stainless steel durability and rubber seat performance, this wafer butterfly valve delivers exceptional value for water treatment, HVAC, and industrial applications requiring cost-effective flow control solutions.
