DELCO Manual Cast Iron Wafer Butterfly Valve, Worm Gear, PN10/PN16 (Class 125), DN06-DN100
Designed for general water and HVAC applications, this cost-effective butterfly valve features a Cast Iron (GG25/GGG40) body with a compact wafer connection. Operated by a smooth worm gear, it provides reliable bubble-tight shutoff (Zero Leakage) for low-to-medium pressure systems (PN16/Class 125) ranging from DN06 to DN100 .
Size Range: DN40-DN1200
Material: CI, WCB, Stainless Steel etc.
Cnnection Standard: GB/ANSI/JIS
Features
An economical, gear-operated cast iron butterfly valve with wafer connection, delivering zero-leakage isolation for water and air lines.
✅Economical Cast Iron Body: Manufactured from durable Cast Iron or Ductile Iron, offering a cost-efficient solution for non-corrosive media like water and air compared to expensive Stainless Steel Butterfly Valves.
✅Easy Worm Gear Operation: The installed gearbox reduces operating torque, allowing for slow, controlled opening and closing to prevent water hammer, which is superior to simple lever handles on larger sizes.
✅Space-Saving Wafer Style: The wafer body is designed to be clamped between pipe flanges, requiring significantly less installation space and structural support than heavy flanged or gate valves.
✅Reliable Soft Seating: Features a resilient EPDM or NBR seat that ensures a bubble-tight seal (Class A Zero Leakage) at standard pressures (PN10/16), ideal for commercial plumbing and irrigation.
✅Standard Pressure Rating: Rated for Class 125 / PN16 service, perfectly matching the requirements of standard municipal water grids, cooling towers, and fire protection systems.
