BDK Two-Piece Ball Valve

Products BDK Two-Piece Ball Valve (Split Body Design)

High-Performance Industrial Isolation Valves for Versatile Process Pipelines
The BDK Two-Piece Ball Valve (also known as a split body ball valve) features a robust two-part casing bolted together securely along the pipeline axis. This distinct engineered design allows for straightforward field maintenance, seal replacement, and internal inspection without requiring complex machining setup.

As a trusted authorized BDK valves dealer, we supply 100% authentic, factory-tested two-piece floating and trunnion-mounted ball valves. These valves provide zero-leakage isolation across standard and high-severity industrial systems handling oil, water, gases, and processed chemicals.

Key Features and Performance Benefits

  • Split-Body Inline Serviceability: The distinct two-piece construction features a main body and an adapter section. This layout allows maintenance teams to access internal components, seats, and seals with minimal pipeline interruption.
  • Full Bore Flow Efficiency: Standard full-port variants ensure an unrestricted flow path matching the pipe's internal diameter. This minimizes turbulence, prevents fluid drag, and keeps pipeline pressure drops to a minimum.
  • Dual Sealing & Fire-Safe Protection: Equipped with resilient soft seats (PTFE / RPTFE / PEEK) for bubble-tight shut-off. If a fire destroys the soft seats, a secondary metal-to-metal seating mechanism automatically triggers to prevent hazardous downstream leaks.
  • Sturdy Stem & Packing Assemblies: Features a blow-out proof stem design along with live-loaded packing configurations. This ensures reliable packing integrity and zero fugitive emissions over long-term operating cycles.
  • ISO 5211 Actuation Top Flange: Comes with integrated standardized top mounting pads for simple installation of pneumatic, electric, or hydraulic actuators for remote flow automation.

Common Industrial Applications

The BDK two-piece split body valve is highly versatile and widely trusted across heavy utilities:

  • Chemical & Processing Lines: Transporting acids, alkalis, solvents, and volatile organic substances safely.
  • Hydrocarbon Infrastructure: Mainline refinery piping, storage terminals, and natural gas transport networks.
  • Power Plants: Auxiliary cooling lines, condenser loops, and low-pressure water systems.
  • Water Treatment Facilities: High-volume raw water piping, desalination plants, and industrial wastewater treatment.
