Our 16 Inch Class 600 ASTM A105 Trunnion Mounted Ball Valve, also known as fixed ball valve, is heavy-duty isolation equipment designed for high-pressure large-diameter pipeline systems. Manufactured from forged ASTM A105 carbon steel, the valve strictly follows API 6D, ASME B16.34 and relevant international standards. The trunnion supported ball structure greatly reduces operating torque, delivering stable sealing performance under Class 600 working pressure. Available with flanged RF / RTJ ends, full bore design, gear operation, optional soft seat or metal seat solutions. Widely adopted in natural gas, crude oil, petrochemical, power station and industrial piping systems.
Trunnion Mounted Fixed Ball Structure Ball supported by upper & lower trunnions, low operation torque, long service life under high pressure.
Forged ASTM A105 Carbon Steel Body Excellent mechanical strength, stable performance for medium & high temperature working conditions.
Anti-Blowout Valve Stem Design Prevent stem ejection under abnormal pipeline pressure, improve site operation safety.
Dual Seal & Emergency Seal Injection System (Optional) On-line seat leakage repair without valve removal.
Fire Safe Construction (API 607) Maintain sealing integrity during fire accidents, ideal for flammable media.
Built-in Anti-Static Device Discharge static electricity between ball and body, avoid explosion risks for oil & gas service.
ISO 5211 Direct Mounting Pad Convenient to install pneumatic, electric or hydraulic actuators for automatic control.
Full Bore Passage Minimum flow resistance, convenient for pipeline pigging operation.
