Product Detail

The High Performance Aluminium Bronze ASTM B148 API 609 Monel Trim Butterfly Valve is a top-tier, corrosion-resistant flow control solution engineered specifically for marine systems, offshore platforms, seawater desalination plants, and aggressive coastal industrial applications. Manufactured in strict compliance with API 609 (Category B), this double-offset high-performance butterfly valve utilizes a robust body cast from ASTM B148 C95800 Nickel-Aluminium Bronze, providing extraordinary resistance to seawater cavitation, marine erosion, and biofouling. Trimmed with Monel (K500/400) shafts and disc components, it prevents galvanic corrosion and stem jamming while delivering low operating torque and bi-directional, bubble-tight zero-leakage shut-off under continuous marine exposure.

Design Description

ASTM B148 Aluminium Bronze Body: C95800/C95500 bronze alloy delivers superior resistance to biofouling, seawater erosion-corrosion, and pitting in brackish and high-salinity marine fluids.
Monel Alloy High-Integrity Trim: Monel shafts and disc components provide exceptional yield strength and immunity to marine galvanic attack and stress cracking.
API 609 Double-Offset Design: Camming action of the double-eccentric disc minimizes seat contact and friction during opening and closing, extending seat life and lowering actuation power requirements.Bi-Directional Bubble-Tight Sealing: Configured with renewable RTFE/PTFE or metal-to-metal seats to achieve absolute zero leakage in line isolation and control loops.
