DOUBLE FLANGE BUTTERFLY VALVE VOYAGE MARINE AUTOMATION High-Pressure Isolation

The DOUBLE FLANGE BUTTERFLY VALVE VOYAGE MARINE AUTOMATION is a heavy-duty, bidirectional quarter-turn isolation valve designed for high-pressure marine pipelines, ballast water systems, and industrial fluid processing networks. Featuring integral double-flanged end connections, this valve allows for secure bolting directly to adjacent pipe flanges, providing maximum structural rigidity, superior resistance to pipeline bending stresses, and easy downstream piping disassembly under full pressure.

Manufactured in accordance with international piping standards—including API 609, AWWA C-504, BS 5155, and JIS 10K—the DOUBLE FLANGE BUTTERFLY VALVE VOYAGE MARINE AUTOMATION is inspected and shell/seat pressure tested under API 594 and BS 5155 specifications. Available in nominal pipe sizes up to 500 mm (with larger diameters above 500 mm engineered upon request), it supports full integration with manual gearboxes, pneumatic actuators, hydraulic power units, and single-phase or three-phase electric actuators.

Key Features of the DOUBLE FLANGE BUTTERFLY VALVE VOYAGE MARINE AUTOMATION

• Robust Double Flange Body: Features full-face flange bolting, offering high structural stability, dead-end service capability, and vibration damping in heavy maritime piping networks.

• Multi-Standard Compliance: Designed and dimensioned per API 609, AWWA C-504, BS 5155, and JIS 10K standards for seamless global fleet drop-in replacement.

• API 594 & BS 5155 Inspection Tested: 100% factory shell and seat tightness pressure tested to guarantee bi-directional leak-free performance under severe operating head pressure.

• Versatile Automation & Drive Options: Compatible with manual worm gearboxes, pneumatic actuators, hydraulic actuators, and 1-Phase / 3-Phase electric motor drives for automated central control rooms.

• Marine Metallurgy Options: Crafted in high-grade alloys—Gunmetal (GM), Nickel Aluminium Bronze (NAB), Stainless Steel (CF8/CF8M), and Cast Carbon Steel (WCB)—for extreme resistance to saltwater corrosion, cavitation, and erosive fluids.

• Large Diameter Capacity: Standard sizes available up to 500 mm nominal bore, with custom sizes above 500 mm manufactured directly by Voyage Marine Automation.

Primary Applications

• Maritime Shipboard Systems: High-volume ballast water treatment systems, sea chest suction networks, bilge discharge, and main engine cooling loops

• Offshore Facilities: Seawater injection pumps, firemain ring lines, and crude oil transfer skids

• Industrial & Water Infrastructure: Desalination plants, raw water intake pumping stations, and municipal water distribution headers
