Conquer the Most Demanding Applications: The WEY SISTAG FB Series Full Bore Knife Gate Valve

When faced with challenging media, highly abrasive slurries, dense suspensions, or critical pipeline pigging operations, conventional valve solutions are prone to failure, leading to costly downtime and maintenance. Through our partnership, LİNDER delivers the definitive engineered solution: the WEY SISTAG FB Series Full Bore Knife Gate Valve. This product represents far more than a simple valve; it is a comprehensively designed system built to dominate the most severe industrial applications. It is the trusted choice in Turkish thermal power plants combating invasive mussel biofouling, in mining operations managing dense and abrasive tailings, and in water treatment facilities handling aggressive sludges.

Unmatched Design Philosophy for Maximum Operational Integrity

The FB Series ingeniously integrates WEY SISTAG’s legendary and robust middle-flange design with a truly unobstructed, full-round bore. This unique architectural synergy delivers unmatched operational reliability while facilitating effortless and effective pipeline cleaning with standard pigs. This eliminates process bottlenecks, ensures maximum flow capacity, and guarantees long-term performance in your most critical process lines.

Industry-Benchmark Design Features: Engineering for Lifecycle Value

1. Self-Cleaning Gate Mechanism

Integral bronze scrapers automatically clean both sealing surfaces of the gate during every opening and closing cycle. This patented feature prevents material build-up, ensures consistent sealing performance over time, and is critically proven in combating seal failure caused by invasive species in water systems, maintaining the full operational diameter.

2. Live-Loaded, Externally Adjustable Transverse Seal

The patented transverse stem seal can be safely, easily, and efficiently repacked at any time—even under full line pressure—using externally accessible lateral packing screws. This revolutionary feature dramatically reduces planned maintenance downtime, enhances operational safety by avoiding system depressurization, and extends valve service life.

3. Mechanical End Position Support

In the fully closed position, the gate is mechanically supported directly by the valve body, independent of the seat. This provides an essential failsafe layer of security against extreme differential pressure, preventing seat distortion and overload for exceptional long-term sealing integrity.

4. True, Unobstructed Full-Bore Design

A perfectly round, smooth, and continuous flow passage enables easy, efficient, and complete pipeline cleaning with standard pigs. This ensures maximum possible throughput, prevents sediment accumulation within the valve body, and is essential for hygiene-critical or piggable pipelines.
