Engineered for Extremes: The TW20 Swiss Butterfly Valve – Exclusively from LINDER, Your WEY SISTAG Partner in Turkey
This is the fundamental challenge that LİNDER ENDÜSTRİ DIŞ TİCARET LİMİTED ŞİRKETİ is engineered to solve. As the official and authorized dealer for WEY SISTAG on the territory of Turkey, we bridge the gap between renowned Swiss precision engineering and the robust demands of the Turkish industrial landscape. We are proud to introduce the definitive solution for reliable, cost-effective flow control: The TW20 Series Butterfly Valve by WEY SISTAG.
Forged in the tradition of meticulous Swiss craftsmanship, the TW20 represents a paradigm shift. It answers the global call for a valve that does not force a choice between unwavering durability and exceptional value. It meets and exceeds ISO PN10/16 standards, integrating state-of-the-art manufacturing techniques to deliver tremendous reliability at a truly competitive price point, making superior engineering accessible for critical projects across Turkey.
Unmatched Engineering: The Definitive TW20 Advantage
Beyond its specifications, the TW20’s superiority is rooted in intelligent, application-focused design details that deliver tangible performance benefits where it matters most.
Robust, Versatile Construction for Maximum System Integrity
The TW20 features a centric design with a wafer-type body, engineered for seamless and secure integration into diverse piping systems. With a comprehensive nominal size range from DN 25 to DN 1200, it is equipped to handle virtually any flow capacity requirement in Turkish industry. Available in critical materials including Stainless Steel (AISI 316), Ductile Iron (GGG40/50), and specialized alloys, each valve is purpose-built to withstand the specific chemical, thermal, and abrasive challenges of your sector.
Superior Bidirectional Sealing Technology
A key innovation that eliminates installation error and enhances operational flexibility is the TW20’s bidirectional pressure capability. The special, precision-molded geometry of its high-grade EPDM seal ensures flawless, leak-tight performance regardless of pressure direction. This is complemented by integrated sealing lips on the liner, guaranteeing excellent flange tightness to protect both your process integrity and the surrounding environment.
Advanced Protection Against Corrosion & Wear
Long-term reliability starts with surface protection. The TW20’s body is shielded by a high-performance EKB epoxy powder coating. Far more than standard paint, this coating provides outstanding mechanical resistance and formidable defense against a wide spectrum of aggressive chemicals, solvents, and atmospheric conditions, dramatically extending service life in Turkey’s most punishing industrial environments.
Hydrodynamically Optimized for Peak Efficiency
At its core, the TW20 features a spherical disc with precision-polished edges. This advanced hydrodynamic design minimizes flow turbulence, reduces pressure drop, and ensures smooth, laminar flow. The result is enhanced energy efficiency for your systems and significantly reduced wear on the disc and seal assembly, contributing to a longer, maintenance-free operational lifecycle.
