3 Piece Trunnion Mounted Ball Valve

Constructed from solid A105N forged body, this 300LB api 6d trunnion mounted ball valve features dense grain structure and remarkable mechanical strength to withstand rigorous high-pressure service. Hot forging refining optimizes internal metal texture without inherent casting flaws, greatly lifting tensile performance and anti-fatigue capacity against frequent pressure surge. Reasonably arranged connecting bolts lock split valve segments firmly, while reserved grease fitting enables convenient on-line lubrication maintenance. It serves as dependable fluid control equipment for refining, natural gas and petrochemical high-pressure piping systems.

Designed with compact bolted split structure, this high-pressure forged ball valve greatly boosts overall body tightness and reliably blocks medium leakage across fluctuating working pressure. Multiple high-strength hex bolts evenly distribute fastening load on split joint surfaces to compress sealing gaskets uniformly. Besides outstanding sealing performance, the split layout enables partial disassembly without full pipeline removal for inner component inspection and replacement. Equipped with lifting lugs on both sides to facilitate hoisting installation for large-size heavy-duty valve on industrial piping projects.

The matched worm gear box adopts space-saving compact layout with robust cast housing. Precisely machined worm wheel and worm inside deliver steady output torque, allowing the large-size ball valve to complete smooth on-off operation with little manpower. Embossed OPEN/SHUT signs plus position indicator directly display valve opening status for quick onsite inspection. Its standard top flange interface supports later installation of electric drive parts, satisfying flexible manual or automatic control requirements for high-pressure petrochemical and gas pipeline projects.
