DELCO Manual Metal Seated Butterfly Valve, Wafer, PN16-PN40 / Class 150-300, DN06-DN100
Engineered for high-pressure and high-temperature service, this metal-seated butterfly valve features a robust wafer body compatible with PN16-PN40 (Class 150-300) flanges. Constructed from WCB or Stainless Steel with hard-faced internals, it ensures reliable isolation in severe conditions where soft seats fail.
Size Range: DN40-DN1200
Material: CI, WCB, Stainless Steel etc.
Cnnection Standard: GB/ANSI/JIS
Features
A high-performance metal-seated butterfly valve with wafer connection, rated up to PN40/Class 300 for durable shutoff in steam and abrasive media.
✅High-Pressure Metal Sealing: Designed with a metal-to-metal seat interface (Stellite/SS) to withstand pressures up to PN40/Class 300 and temperatures exceeding 250°C, surpassing the limits of rubber-seated valves.
✅Compact Wafer Connection: The wafer-style body fits efficiently between standard flanges (DIN/ANSI), offering a lighter, space-saving alternative to bulky Gate Valve or Globe valves in high-pressure lines.
✅Triple Eccentric Performance: (Often applicable) Leverages a triple-offset geometry to eliminate friction during disc movement, ensuring bubble-tight shutoff (Zero Leakage) even at higher pressure classes.
✅Robust Body Materials: Available in Cast Steel (WCB) for standard steam/oil applications and Stainless Steel (CF8M) for corrosive chemical resistance, matching the pipeline’s pressure rating.
✅Wear & Abrasion Resistance: The hardened metal seat resists erosion from high-velocity fluids and particulates, maintaining seal integrity longer than soft-seated equivalents in throttling duties.
