Fire-Safe & Anti-Static Trunnion Mounted Worm Gear Flanged Ball Valve for Natural Gas (DN50–DN1400, ASME 150–2500) | DELCO
DELCO Fire-Safe & Anti-Static Trunnion Mounted Worm Gear Flanged Ball Valve is designed for natural gas isolation in pipeline and station services. The trunnion-mounted structure and worm gear operator provide stable shut-off and controlled operation on larger sizes. Fire-safe and anti-static design features support safer performance in gas applications where ignition risk and emergency isolation are key concerns. It covers DN50–DN1400 with ASME Class 150–2500, and flanged ends can be supplied to match GB/ANSI/DIN/JIS piping standards.
Size Range:DN50-DN1400 ASME ClaSS:ASME 150~2500LB
API Standard:API 2000~15000
Connection Standard:GB / ANSl/DIN /JIS
Features
Fire-safe and anti-static design combined with trunnion mounting provides safer, more controllable isolation for natural gas pipeline duties.
✅Fire-Safe Design for Emergency Conditions: Designed to maintain isolation capability under fire exposure scenarios, supporting safety-critical gas service requirements.
✅Anti-Static Feature for Gas Applications: Provides a conductive path to reduce electrostatic charge accumulation during operation in gas service.
✅Trunnion Mounted Structure (Stable Shut-Off): Fixed-ball design improves stability and helps reduce operating torque, especially in larger DN sizes.
✅Worm Gear Operator for Large Valves: Gear-driven handwheel enables smoother, controlled operation and safer handling in high-torque conditions.
✅Wide Size & Pressure Range + Multi-Standard Flanges: DN50–DN1400 and ASME Class 150–2500; flanged ends can match GB / ANSI / DIN / JIS.
