Bronze Three Piece Ball Valve<\/h1>\n

TECHNICAL DATA SHEET<\/h1>\n

Product:<\/strong>\u00a0Three-Piece Trunnion Mounted Ball Valve
\nMaterial:<\/strong>\u00a0ASTM B150 C63200 (Forged Aluminum Bronze)
\nActuation:<\/strong>\u00a0Actuator-Ready (ISO 5211 Direct Mount Platform)<\/p>\n

\n

1. General Description<\/h3>\n

This valve is manufactured from\u00a0ASTM B150 C63200<\/strong>\u00a0forged aluminum bronze. The three-piece body design allows easy in-line maintenance without removing the valve from the pipeline. The trunnion-mounted ball provides low operating torque and reliable sealing under high pressure and large bore conditions. Forged C63200 offers a dense grain structure, superior yield strength, and excellent resistance to seawater corrosion, cavitation, and fatigue. The valve features an integrated ISO 5211 top flange for direct actuator mounting without brackets.<\/p>\n

4. Key Features<\/h3>\n
    \n
  • \n

    Three-Piece Body Construction:<\/strong>\u00a0Center section and two end caps allow quick disassembly for maintenance without removing the valve from the pipeline.<\/p>\n<\/li>\n

  • \n

    Trunnion Mounted Ball:<\/strong>\u00a0Ball is supported by upper and lower trunnion bearings, reducing stem torque and enabling smooth operation even at high pressures and large diameters.<\/p>\n<\/li>\n

  • \n

    High-Strength Forged Material:<\/strong>\u00a0Manufactured from\u00a0ASTM B150 C63200<\/strong>\u00a0forged aluminum bronze with typical tensile strength exceeding\u00a0620 MPa (90 ksi)<\/strong>\u00a0. Provides outstanding resistance to seawater corrosion, cavitation erosion, and flow abrasion.<\/p>\n<\/li>\n

  • \n

    ISO 5211 Direct Mount Platform:<\/strong>\u00a0Top flange machined to ISO 5211 standards. Enables direct actuator attachment without a mounting bracket, ensuring perfect alignment and reducing potential leak paths.<\/p>\n<\/li>\n

  • \n

    Blowout-Proof Stem:<\/strong>\u00a0Stem is positively retained against internal pressure for enhanced safety.<\/p>\n<\/li>\n

  • \n

    Anti-Static Device:<\/strong>\u00a0Conductive path between ball, stem, and body dissipates static charges for applications in flammable environments.<\/p>\n<\/li>\n<\/ul>\n

    \n

    5. Actuator Interface (ISO 5211)<\/h3>\n

    The valve top flange complies with ISO 5211 for easy automation.<\/p>\n
