DELCO Worm Gear Metal Seated Flanged Butterfly Valve, Class 150/300 (PN16-PN40), DN06-DN100
Designed for precise throttling and heavy-duty isolation, this flanged butterfly valve features a worm gear operator for easy handling of high-torque metal sealing mechanisms. Rated for Class 150/300 (PN16-PN40), the WCB or Stainless Steel body ensures robust performance in high-temperature steam and abrasive media applications.
Size Range: DN40-DN1200
Material: CI, WCB, Stainless Steel etc.
Cnnection Standard: GB/ANSI/JIS
Features
A gear-operated, double-flanged metal seated butterfly valve designed for high-pressure durability and zero-friction closure in severe industrial lines.
✅Worm Gear Operation: Equipped with a heavy-duty gearbox that reduces operator effort and eliminates water hammer, providing smooth, self-locking control compared to lever-operated models.
✅Double Flanged Stability: Features a double-flanged body design that allows for secure bolting to pipeline flanges (RF/FF), offering superior mechanical stability for end-of-line service compared to wafer types.
✅High-Temp Metal Sealing: The hard-faced metal seat (Stellite/SS) withstands temperatures up to 450°C and resists abrasion, making it a reliable alternative to a Gate Valve in thermal power plants.
✅Pressure Handling: Engineered for PN16 to PN40 (Class 150-300) ratings, utilizing a triple-offset geometry to ensure bubble-tight shutoff even under high differential pressures.
✅Material Versatility: Available in Cast Steel (WCB) for general high-pressure duties and Stainless Steel (CF8M) for corrosive environments, ensuring long-term structural integrity.
