Conquer the Most Demanding Applications: The WEY SISTAG W Series Knife Gate Valve
The Pinnacle of Swiss Severe-Service Engineering
The WEY SISTAG W Series represents the culmination of decades of relentless Swiss pursuit of perfection. Born from a philosophy that no application is too severe, this valve series has been engineered to its absolute limits. The result is a product offering unparalleled flexibility across nominal sizes (50 – 1400 mm), material grades, and pressure ratings (0 – 50 bar), creating an incredible scope of industrial application. We guarantee it will outperform conventional alternatives in any severe-service situation encountered in Turkey’s robust industrial landscape.
Unmatched Design. Uncompromising Performance.
Bubble-Tight Integrity, Guaranteed
A unique, patented transverse seal system—combining a specialized elastomer profile and advanced packing compound—ensures the valve body is hermetically sealed towards the atmosphere. This critical safety and environmental feature can be repacked under full line pressure at any time via lateral screws, eliminating the need for costly system shutdowns and downtime for maintenance.
Superior Shut-Off and Unobstructed Flow
A mechanically retained, precision-molded round cord seal creates a bubble-tight shut-off on the gate edge. The reinforced gate is mechanically guided and supported through its full stroke, preventing vibration, deflection, and misalignment. The optimized gate geometry actively pushes accumulated media out of the gate guide and back into the flow bore, preventing sediment build-up and ensuring a clean, efficient, and energy-saving flow path.
Engineered for Operational Efficiency
The robust, universal bonnet design accommodates a comprehensive range of actuators (manual handwheel, pneumatic, hydraulic, electric), providing unmatched flexibility. Integrated flange threads significantly simplify field assembly, disassembly, and allow for reliable dead-end service, reducing installation time and labor costs.
Built for Turkey’s Most Critical Industrial Applications
The WEY SISTAG W Series is the valve of choice for sectors where equipment failure translates to significant production loss and safety risks:
Mining & Mineral Processing
Masterfully handles abrasive mining slurry, sinter water, tailings, and process minerals with exceptional wear resistance, ensuring continuity in Turkey’s vital mining sector.
Chemical & Petrochemical
Constructed from material combinations like Stainless Steel 316/316L, Ni-Resist, Duplex Steel, and lined with Aflas or PTFE to withstand highly corrosive media and aggressive process chemistries.
Pulp & Paper Industry
Reliably manages high-density pulp stocks, recycled fiber slurries, and aggressive bleaching chemicals, offering durability that reduces maintenance cycles.
Power Generation & Energy
Built to endure in fly ash handling, FGD (Flue Gas Desulphurization) slurries, bottom ash, and other critical power plant services, contributing to uninterrupted energy production.
Water & Wastewater Treatment
Ideal for raw sewage, sludge, and treated water applications, with configurations that prevent clogging and ensure reliable operation in municipal and industrial treatment plants.
Advanced Material Selection & Corrosion Protection
We offer a comprehensive range of body materials including Carbon Steel (WCB), Stainless Steel (CF8/CF8M), Cast Bronze, and specialized alloys. Critical wear components are available in hardened stainless steel or coated with advanced materials like tungsten carbide. Combined with superior corrosion protection protocols—such as E-coat (electrocoating) for valve bodies and epoxy powder coating for topworks—the W Series is engineered for maximum longevity in Turkey’s diverse and challenging industrial environments.
