API 6D Thru Conduit Gate Valves

Slab Gate Valve (Thru Conduit) Manufacturer: FlowBiz Exports

A Slab Gate Valve features a flat, rectangular gate with a circular opening (conduit). In the fully open position, the conduit aligns perfectly with the pipeline bore, creating a smooth, continuous path. This design is critical for "pigging" operations and applications where minimizing turbulence and pressure drop is essential.

Key Features & Advantages

  • Negligible Pressure Loss: In the fully open position, the flow resistance coefficient is nearly zero. This results in almost no pressure loss, optimizing pumping efficiency across long distances.
  • Double Sealing Technology: Our valves utilize soft-sealing fluoroplastic inlays combined with metal-to-metal contact. This "Double-Sealing" ensures a bubble-tight shut-off even in high-pressure gas services.
  • Self-Cleaning Gate: The fluoroplastic inlays are designed to "wipe" the gate disc during operation, removing dirt and debris to prevent seal damage.
  • Protected Seals: Unlike standard gate valves, the slab gate design ensures the seats are covered and protected from the media in both the fully open and fully closed positions, significantly extending the valve’s service life.
  • Emergency Sealing: Equipped with external grease injection nipples, allowing operators to inject sealant directly to the seat area to achieve bubble-tightness in the event of minor seat damage.
  • Bi-Directional Sealing: The floating seat structure ensures tightness regardless of flow direction or whether the valve is open or closed.

Strategic Applications

FlowBiz Slab Gate Valves are engineered for high-stakes environments:

  • Oil & Gas Pipelines: Ideal for crude oil and natural gas transmission lines.
  • Pigging Operations: The full-bore thru-conduit design allows for the unobstructed passage of pipeline pigs.
  • Refineries: Handling volatile liquids where zero-leakage is a safety requirement.
  • Water & Slurry: Robust enough to handle fluids with suspended solids due to the self-cleaning gate action.
