WEY DP Series Knife Gate Valves: Premium Swiss Engineering for Turkey’s Demanding Industry

For the most demanding industrial applications across Turkey’s key sectors, selecting equipment that unites precision engineering, unwavering durability, and innovative design is critical to operational success. LİNDER ENDÜSTRİ DIŞ TİCARET LİMİTED ŞİRKETİ stands as the official dealer and technical representative for the renowned WEY SISTAG brand in Turkey. We bridge the gap between world-class Swiss manufacturing excellence and the specific needs of Turkish industry, delivering not just premium products, but complete, reliable fluid handling solutions backed by expert local support.

Mastering Challenging Media with Unmatched Swiss Precision

In industries where process integrity and uptime are paramount, conventional valve solutions often prove inadequate. The WEY SISTAG DP Series Knife Gate Valve represents a significant advancement in technology, engineered from the ground up to dominate in applications involving abrasive slurries, viscous pastes, fibrous materials, and media with extremely high solid content—environments where standard valves typically clog, wear prematurely, or fail.

WEY DP Series: The Definitive Solution for Severe Service Solids Handling

Conquer your most challenging flow control applications with the WEY SISTAG DP Series, available exclusively in the Turkish market through your trusted partner, LİNDER. This valve is engineered to excel where others falter. Its signature O-Port gate design seamlessly shears through solid columns and dense media within the pipeline, preventing bridging and ensuring continuous, uninterrupted operation. The critical differentiator is the integrated patented transverse seal system, a feature that elevates the DP model above conventional knife gate valves, guaranteeing superior sealing performance, enhanced reliability, and extended service life in the most punishing conditions.

Key Industrial Application Sectors in Turkey

The robust design and versatile configuration of the WEY DP Series make it the preferred valve for critical processes across a wide spectrum of Turkish industries:

• Mining & Mineral Processing: Durable handling of highly abrasive tailings, slurries, and process water.
• Water & Wastewater Treatment: Reliable operation with raw sewage, sludge, grit, and treated effluent.
• Power Generation & Infrastructure: Dependable performance in Flue Gas Desulphurization (FGD) systems, ash handling, and industrial water circuits.
• Pulp & Paper Industry: Precise control over pulp stocks, recycled fibre slurries, and chemical additives.
• Chemical & Petrochemical Industries: Safe and corrosion-resistant handling of aggressive process slurries and media.
• Biogas & Renewable Energy Plants: Effective management of fibrous substrate mixtures and digestate.
• Cement & Construction Materials: Handling of abrasive cement slurries and process dust.

Technical Specifications & Engineered Design Characteristics

The WEY DP Series is defined by its flexible configuration and rugged, purpose-built construction, allowing for optimal adaptation to your specific process parameters, pressure, and media type.

Core Design Configurations & Specifications

• Nominal Diameter (DN): Comprehensive range from DN 50 up to DN 400 mm.
• Pressure Rating (PN): Engineered for working pressures from 0 (atmospheric) up to PN 25 bar.
• Material Excellence: Manufactured in Stainless Steel (316/304), Cast Iron, Ductile Iron, Cast Steel, and specialized alloys to combat corrosion and wear.
• Flange Compatibility: Standard drilling for PN10, PN16, PN25, and ANSI Class 150, ensuring seamless integration into existing piping systems.
• Face-to-Face Dimensions: Compliant with EN 558 Series 20 standard, with non-standard lengths available for custom applications.

Comprehensive Actuation Solutions for Full Automation

Designed to integrate into any level of automation, the DP Series supports a complete spectrum of actuator types, all mounted on its robust, heavy-duty 4-post topwork engineered for maximum load capacity and stability:

• Manual Handwheel (Lever) for basic applications
• Bevel Gear Operator for reduced manual torque
• Pneumatic Cylinder Actuator for automated on/off duty
• Hydraulic Cylinder Actuator for high-force, high-pressure applications
• Electric Motor Actuator for precise modulating control and seamless PLC/SCADA system integration

Patented Engineering Details That Ensure Operational Success

Through-Gate Design for Uninterrupted Process Continuity

The defining feature of the DP Series is its proven ability to close through a solid column of stagnant media or long-fiber materials. This eliminates costly process interruptions and the need for upstream flow clearing, ensuring reliability even during unexpected line blockages or process upsets.

Robust Topwork & Guaranteed Sealing Integrity

The heavy-duty 4-post yoke assembly provides unmatched stability and alignment for all actuator types, protecting the valve stem and internals. Combined with the innovative, field-replaceable transverse seal, this design guarantees a bubble-tight shut-off, drastically reducing leakage, maintenance frequency, and the total cost of ownership over the valve’s lifespan.
