This DN500 PN25 3-piece trunnion ball valve is fully forged from ASTM A182 F304 stainless steel with excellent anti-corrosion performance.

Trunnion mounted ball design ensures stable sealing under high pressure; matched worm gear box greatly reduces operation torque for large bore valve.

Split three-piece body allows on-site seal replacement without removing the whole valve from pipeline, saving maintenance cost.

Full bore design minimizes flow resistance, perfect for large flow piping system. Integral support legs reduce pipeline load during installation.

Custom options: F316L body, metal to metal seat, electric actuator, suitable for natural gas, seawater desalination, chemical, power plant projects.
