Operated by a manual **worm gear operator (turbine)**, it provides easy and precise control, especially for larger pipe diameters. The core sealing components feature a **CF8M (AISI 316 Stainless Steel) disc** for corrosion resistance and a resilient **EPDM seat** for a dependable, bubble-tight seal. With a comprehensive **size range from DN50 to DN2000**, this valve is built to meet the demands of large-scale infrastructure and industrial projects.

CBF01-TF01-Operation and Maintenance Manual DOWNLOAD
1. High-Strength Pin-Mounted Disc & Stem Assembly for Ultimate Reliability
Our valve incorporates a robust mechanical design that ensures durability and prevents internal failure.
Secure Disc Connection: The **CF8M disc is securely fastened to the stem using high-strength pin connections**. This design prevents disc loosening or slippage under high torque or pressure fluctuations, a common failure point in standard keyed or clamped designs.
Enhanced Structural Integrity: The pin-mounted system distributes operational stresses more evenly between the disc and stem, significantly increasing the valve's resistance to mechanical shock and water hammer, leading to a longer service life.
Maintenance-Free Operation: This permanent, positive-lock assembly eliminates the need for internal adjustments and reduces the risk of component separation, ensuring reliable, maintenance-free operation over time.
2. Efficient Gear Operation for Effortless Large-Diameter Control
Designed for easy manual handling across its extensive size range
High Mechanical Advantage: The **multi-ratio worm gear operator** provides substantial torque multiplication, making the manual opening and closing of large-diameter valves (from DN400 upwards) smooth and manageable with minimal operator effort.
Precise Positioning & Indication: The gearbox allows for fine, incremental disc positioning for potential flow modulation and features a clear, visual position indicator (open/close) for at-a-glance status confirmation.
Reliable Seating: The gear mechanism ensures a tight mechanical seal by applying consistent and adequate seating torque, guaranteeing leak-tight shut-off against the EPDM seat.
3. Durable Material Combination for Water & General Service
Built with proven materials for long-lasting performance in common applications.
Corrosion-Resistant Disc: The **CF8M (AISI 316 Stainless Steel) disc** offers excellent resistance to corrosion and pitting from chlorides and oxidizing agents present in treated water, cooling water, and mild industrial fluids.
Resilient EPDM Seal: The **Ethylene Propylene Diene Monomer (EPDM) seat** provides outstanding elasticity, excellent resistance to water, weathering, and a wide operating temperature range, ensuring a long-lasting, reliable seal.
Robust Flanged Body: The **Ductile Iron (GGG40) body** with **integral flanges (EN1092-2 or ANSI B16.1)** offers high strength and impact resistance, forming a permanent, rigid, and leak-resistant connection to the pipeline.
4. Extensive Size Range (DN50-DN2000) for Major Infrastructure Projects
A scalable solution engineered for large-scale systems.
Unmatched Size Availability: We offer one of the broadest standard ranges in the industry, from **DN50 (2") up to DN2000 (80")**, capable of serving everything from branch lines to main transmission pipes.
Engineered for Large Diameters: Valves in the larger sizes (DN1200+) are specifically designed with reinforced structures and optimized gear ratios to handle the inherent challenges of large-diameter flow control reliably.
Versatile Application Scope: This makes the valve ideal for major **water distribution networks, wastewater treatment plants, power plant cooling systems, and large industrial process water circuits**.
