Slab Gate Valves: Through-Conduit Excellence for Oil & Gas Pipelines
A Slab Gate Valve features a single, solid gate unit that slides between two independent seat rings. Unlike a wedge gate valve, the slab gate’s sealing surfaces are parallel, ensuring that the valve remains unaffected by thermal expansion or body deformation.
The FlowBiz Structural Advantage
Our Slab Gate Valves are designed to handle media containing suspended particles while maintaining the integrity of the pipeline.
- Smooth Bore-Through: When fully open, the valve provides a linear, unobstructed flow path. This results in zero pressure loss and a flow resistance coefficient equivalent to a straight pipe.
- Piggable Design: The smooth bore allows for the easy passage of "pigs" for pipeline cleaning and inspection.
- Thermal Resilience: Even in extreme heat, the lengthening of the stem does not damage the sealing surface, preventing the "jamming" common in wedge-style valves.
- Self-Positioning Seats: The floating seat design ensures that the valve achieves a perfect seal even if the gate position is not perfectly centered.
Core Applications & Configurations
FlowBiz Slab Gate Valves are customized for specific upstream and midstream requirements:
Application | Recommended Valve Type |
Mainline Oil & Gas Pipelines | Single or Double-Disc Slab Gate Valves. |
Wellhead Recovery Devices | Slab Gate Valves with Diversion Holes and floating seats. |
Product Storage & Refineries | Single or Double-Gate units without diversion holes. |
Cleaning-Intensive Lines | Through-Conduit designs for pluggable/piggable methods. |
Key Features of FlowBiz Slab Gate Valves
- Debris Management: The sliding action of the gate between the seats naturally wipes the sealing faces clean, making them ideal for media with broken particles.
- Floating Seats: Our seats are spring-energized or pressure-energized to ensure a tight seal at both low and high pressures.
- Low Maintenance: The simple, robust design requires less frequent servicing than complex globe or wedge valves.
- Rising Stem Design: Provides a clear visual indicator of the valve’s open or closed status.
