CBF02-TA(L)01-Lug Type Butterfly Valve with no-pin design_10

Technical Features & Advantages:

1. Precision Polished Disc Surface

Mirror Finish: Ra ≤ 0.4μm surface finish minimizes friction and prevents particle adhesion
Enhanced Durability: hard-facing on disc edge for abrasion resistance
Corrosion Resistance: 316L/316SS disc with optional super duplex 2507 for chloride environments

2. Wafer Space-Saving Design

Compact Construction: 40% lighter than lug-type valves with identical pressure rating
Easy Installation: Fits between ANSI B16.5 or DIN EN 1092-1 flanges
Cost Efficiency: Reduced material and installation costs

3. Operational Excellence

Long Service Life: 100,000+ cycles in abrasive service conditions
Multiple Actuation Options: Compatible with manual lever, gear operator, or ISO 5211 standard actuators.
Visual Position Indication: Clear open/close status for operational safety and convenience.

4. SS Valve Body Advantages

Superior Corrosion Resistance：SS valve bodies (typically 304/316 stainless steel) demonstrate exceptional resistance to chemical corrosion, oxidation, and pitting, particularly in chloride-rich environments. This extends valve service life by 3-5× compared to carbon steel in aggressive media like seawater, acids, and chemical processing fluids, while eliminating external coating requirements.
Hygienic & Low Maintenance：With electropolishing capability (Ra≤0.8μm) and non-porous surfaces, SS bodies prevent bacterial growth and particle adhesion, meeting FDA/USP Class VI standards for pharmaceutical and food applications. The material's inherent durability eliminates corrosion-related maintenance while enabling full CIP/SIP cleaning compatibility.

5. Quality Assurance & Compliance

ISO 9001 Certified Manufacturing: Ensures consistent quality control throughout production process
International Certifications: CE, UKCA, and WRAS approvals guarantee compliance with global market requirements
Material Traceability: Full documentation and material certifications available for quality verification
