BELVEN BV10 DUCTILE IRON BUTTERFLY VALVE, WAFER TYPE WITH GEAR OPERATED, NBR, SS304

The Belven BV10 Ductile Iron Gear-Operated Butterfly Valve is built for high-capacity industrial pipe systems requiring smooth, high-torque manual control and bubble-tight isolation. Constructed with a heavy-duty Ductile Iron (GGG40) body, a SS304 Stainless Steel disc, and an oil-resistant NBR seat liner, this valve ensures reliable performance in oil, gas, wastewater, and general industrial service.

Key Features & Design Highlights

• Worm Gear Box Actated: Heavy-duty, weatherproof worm gear operator with position indicator for effortless open/close operation under high pressure differentials.
• Ductile Iron Construction: High tensile strength GGG40 ductile iron body coated with protective epoxy for resistance to mechanical stress and external corrosion.
• NBR Oil-Resistant Seat: Specially formulated Nitrile (NBR) vulcanized seat liner provides excellent resistance to hydrocarbons, mineral oils, and industrial effluents.
• Wafer Centering Lugs: Universal wafer body geometry with multi-flange location holes for easy alignment between counter-flanges.
• Blow-Out Proof Two-Piece Stem: Dual-shaft design minimizes internal flow resistance while preventing stem blow-out under peak working pressure.

Recommended Applications

Suitable for oil and fuel transport lines, industrial wastewater processing, compressed air systems, raw water intake, and general manufacturing fluid handling.
