Butt Weld Triple Offset Butterfly Valve

The Butt Weld Triple Offset Butterfly Valve is a high-performance industrial valve designed with a triple eccentric structure, featuring a metal seated sealing mechanism for bidirectional leak-tight operation under extreme temperatures and pressures. Engineered for butt-welded pipeline connections, it integrates a robust body (typically made of carbon steel, stainless steel, or alloy steel) with a unique three-axis offset disc rotation that minimizes friction and wear while ensuring precise alignment during closure. This design enables superior sealing capabilities, corrosion resistance, and extended lifespan, making it ideal for harsh environments in oil/gas, chemical processing, and high-pressure water systems. Compliance with standards like API 609 ensures reliability in critical applications, while optional fire-safe certifications (e.g., API 607) enhance safety in flammable settings.

This kind of butterfly valve adopt three-dimensional eccentric principle to design, So it makes the movement track on facing space reach

to idealization, and there are no attrition and no intervene between

hermetical components, furthermore, the hermetical material has been

selected reasonably, thereby it ensure hermetic, 10.antisepsis,wear

able capability of valve.

Product features of butt weld triple offset butterfly valve：

1. Tiny moment for starting, flexible and convenient, save labor and energy

2. Three-dimensional eccentric configuration forces disc close tighter

and tighter, and reach to reliable hermetic capability and with no leakage

3. It has characteristic of high temperature resistant, high pressure

resistant, antisepsis, wearable, long service life etc

The Butt Weld Triple Offset Butterfly Valve is designed for high-performance sealing and durability in industrial pipelines. Below are key installation and maintenance considerations:

Installation：

Ensure proper alignment with pipeline ends to avoid stress on the valve body. Weld according to ASME or EN standards, using full-lug (T4) or flanged (T7) designs for secure connections.

Verify torque settings on bolts and adjust sealing components (e.g., graphite/metal layers) to prevent leaks. Avoid over-tightening, which may damage seals.

Maintenance：

Regularly inspect seals, stems, and bearings for wear or corrosion. Clean surfaces with non-abrasive tools to remove debris.

Lubricate moving parts (e.g., actuators, cams) with manufacturer-recommended grease to ensure smooth operation.

Monitor for abnormal noises or vibrations, which may indicate misalignment or internal damage.

Operational Care：

Avoid sudden pressure fluctuations during operation. Use speed control devices if needed to reduce dynamic torque stress.

For fire-safe models, conduct annual certifications per ISO 10497/BS 6755 standards to maintain safety compliance.

Storage & Handling：

Store valves in dry, corrosion-free environments. Protect against physical impacts during transportation.
