Engineered for Extremes: The WEY SISTAG TF20 Butterfly Valve – Your Ultimate Flow Control Solution

Unmatched Versatility and Robust Design of the WEY SISTAG TF20 Valve

The TF20 Series is engineered with a versatile short face-to-face, double flange design, ensuring seamless compatibility with the world’s most common standards including DIN, ANSI, and BS. This makes it the ideal choice for a vast array of applications, particularly for critical installations at the line end or anywhere a robust, double-flanged valve is required.

Its core strength lies in a design philosophy that refuses to compromise. Built for pressures from 0 to 25 bar (PN10, PN16, PN25, ANSI Class 150) and available in an impressive size range from DN 80 to 2500 mm, the TF20 is prepared to handle your scale, your pressure, and your most challenging process conditions.

Key Technical Characteristics That Set the TF20 Apart

• Centric Butterfly Valve Design: Delivers reliable and efficient shut-off and control for a wide spectrum of media, from water to aggressive chemicals.
• Bidirectional Pressure Sealing: A proprietary seal design allows for pressure from both sides, offering unparalleled installation flexibility and operational security.
• Spherical Disc with Polished Edges: This advanced disc geometry minimizes turbulence, reduces wear on the sealing surface, and ensures a perfect, lasting seal with every operation, enhancing valve life.
• Superior Flange Tightness: Integrated sealing lips on the liner create an exceptional seal against the flange, virtually eliminating leakage and protecting your system integrity and environmental safety.

Built to Endure Your Toughest Industrial Environments

The WEY SISTAG TF20 is not a generic product; it is a tailored fortress engineered for specific media and extreme conditions across key industries in Turkey and beyond.

Primary Application Areas

• Mining & Minerals Processing: Engineered to resist highly abrasive slurries, acidic effluents, and phosphate solutions.
• Chemical & Petrochemical Industry: Handles aggressive, chemically contaminated wastewater, process fluids, and various acids and alkalis.
• Water Treatment & Infrastructure: The trusted choice for industrial water circuits, mixed water systems, and potable water networks, ensuring reliable flow control.
• Food & Beverage Production: Manufactured with hygienic considerations for handling syrups, juices, beverages, and CIP (Cleaning-in-Place) fluids.
• Marine & Power Generation: Provides exceptional corrosion resistance against seawater, saltwater, and cooling water treatment chemicals.

Material Integrity & Advanced Customization

Standard Construction: Features a Ductile Iron body (EN-GJS-400-15) with a robust EKB powder coating for superior corrosion protection. The disc is crafted from Stainless Steel (1.4408), and the shaft from AISI 420, ensuring high torsional strength and resistance to wear. The EPDM seal provides excellent chemical and temperature resistance.

Full Customization: Beyond the standard, we offer the TF20 in a multitude of other materials, including Cast Iron, Carbon Steel, Cast Bronze, and Special Alloys like Duplex and Hastelloy, upon request, to meet your precise corrosive or high-temperature requirements.
