Uncompromising Swiss Engineering for Turkish Industry

The WEY SISTAG TL20 Butterfly Valve represents the zenith of centric disc valve design, conceived for general industrial applications where durability, safety, and cost-efficiency converge. It embodies a philosophy where robust construction meets intelligent design, offering a superior alternative to traditional valves and setting a new benchmark for reliability in water treatment, chemical processing, mining, and infrastructure projects across Turkey.

Unmatched Versatility & Robust Design: The TL20 Advantage

Beyond a simple component, the TL20 is a strategic investment in system integrity. Its defining lug-type body design provides exceptional versatility, serving as a direct and cost-effective replacement for more complex double-flange valves. This pivotal feature allows for the isolation of pipeline sections for maintenance without a full system shutdown, minimizing downtime and maximizing operational continuity.

Key Technical Characteristics & Superior Performance

• Precision Engineering: A true centric butterfly valve design ensures optimal sealing geometry and smooth, low-torque operation cycle after cycle.
• Material Superiority: Available in Stainless Steel (1.4408), Ductile Iron (EN-GJS-400-15), Carbon Steel, and specialized alloys to resist corrosion, abrasion, and chemical degradation in the toughest environments.
• Bidirectional Sealing Integrity: Features a uniquely profiled EPDM seal engineered for pressure-tight shut-off from both sides of the disc. Integrated sealing lips on the liner guarantee excellent flange tightness, eliminating leakage.
• Optimized Hydrodynamics: The spherical disc with precision-polished edges minimizes flow turbulence, reduces pressure drop, and ensures efficient, bubble-tight closure, enhancing overall system energy efficiency.
• Durable Protection: The valve body is shielded by a resilient EKB powder coating, providing outstanding mechanical strength and high resistance to a broad spectrum of chemicals and solvents.

Built to Endure: Standard Construction & Specifications

Transparency in quality is paramount. The standard construction of the TL20 valve showcases its inherent durability and design excellence:

• Body: Ductile Iron (EN-GJS-400-15)
• Disc: Stainless Steel (1.4408)
• Seal: EPDM (offering excellent chemical and temperature resistance)
• Shaft: AISI 420 (for high torsional strength and corrosion resistance)
• Shaft Bearing: Acetal / Steel bronze PTFE / Bronze (ensuring smooth, low-friction operation and extended service life)

Range: Sizes from DN 25 to DN 1000 | Pressure rating up to PN 16 / 25 bar.
