  1. Features & Applications
  • Key Features:
    • Trunnion Mounted Design: The ball is supported by upper and lower trunnions (bearings), reducing operating torque and enabling high-pressure, large-size applications .
    • Reduced Bore (4″x3″): Optimized flow path for pressure drop management and cost efficiency.
    • Double Block & Bleed (DBB): Provides positive isolation from both upstream and downstream pressure, with the ability to bleed/vent the body cavity .
    • Emergency Sealant Injection: Fittings allow injection of sealant into seats and stem in case of seal damage, providing emergency shut-off capability .
    • Cavity Pressure Relief: Self-relieving seats prevent dangerous over-pressure in the ball cavity due to thermal expansion .
    • Anti-Static Device: Ensures electrical continuity across the valve to prevent spark ignition in flammable services .
    • Fire-Safe Design: Optional API 607/6FA certification ensures sealing integrity in case of fire .
    • Blow-out Proof Stem: Stem is retained within the valve body even if the gland is removed under pressure .
    • ISO 5211 Mounting Pad: Standardized mounting for easy actuator installation .
    • Bidirectional Sealing: Suitable for flow in either direction.
  • Main Applications:
    • Oil & Gas Pipelines: Transmission and distribution lines requiring DBB isolation .
    • Refineries & Petrochemical Plants: Hydrocarbon processing, high-pressure fluid handling.
    • Offshore Platforms: Compact design for space-constrained applications .
    • Power Generation: Steam and high-pressure water systems.
    • LNG & Cryogenic Plants: With extended bonnet and low-temperature materials.
    • Subsea & Pipeline Terminals: Where high integrity isolation is required.
