EN 593 PN10/PN16/CLASS 125/ DOUBLE SHAFT BUTTERFLY VALVE
BFV305 306
Product Description
IFLOW butterfly valves with vulcanized seats are critical components in marine applications, providing reliable and efficient control of fluid flow in shipboard systems. Its dual-axis design increases stability and precision, making it ideal for marine environments where consistent performance is critical for safe and efficient operation.
The valve is constructed with a vulcanized seat and is designed to withstand the harsh conditions encountered at sea, including exposure to salt water, extreme temperatures and corrosive elements. Vulcanized valve seats ensure a tight and reliable seal, minimizing the risk of leakage and maintaining optimal operating efficiency even in challenging offshore conditions.
With its durable construction and advanced sealing technology, IFLOW butterfly valves with vulcanized seats are the ideal solution for a variety of marine applications, including shipboard piping systems, ballast water management and seawater cooling systems. Its proven performance and rugged design make it the trusted choice for ensuring safety, efficiency and reliability of fluid control in offshore operations.
