Vanne papillon triple excentration

Vanne papillon triple excentration

Our Triple Offset Butterfly Valve is designed for high temperature, high pressure and severe service applications where dependable shut-off performance, reduced seat wear and long-term reliability are required. With its triple offset geometry and metal seated construction, the valve minimizes friction between the sealing surfaces during opening and closing, making it suitable for more demanding industrial systems than general-purpose butterfly valves.

This valve is widely used in oil and gas, petrochemical, power generation, steam systems, refinery units, chemical processing and other industrial pipeline applications where service conditions require a robust sealing structure and stable operating performance. It can be supplied in different body, disc, shaft and sealing material combinations according to medium, temperature, pressure and project standards.

Caractéristiques principales

• Triple offset design for reduced sealing surface friction
• Metal seated structure for high temperature and severe service
• Suitable for higher pressure and more demanding operating conditions
• Longer service life in frequent operation applications
• Available with manual, pneumatic and electric actuation
• Suitable for steam, oil, gas and industrial process media

Spécifications techniques

Matériaux et construction

The valve body is commonly available in carbon steel, stainless steel or alloy steel for demanding service conditions. Disc and shaft materials are selected according to temperature, corrosion resistance and mechanical strength requirements. The sealing structure is typically metal seated and may include laminated seal rings, graphite or hard-faced sealing materials depending on the application.

The triple offset design creates a cam-like sealing motion that reduces rubbing between sealing surfaces during opening and closing. This helps improve sealing reliability, reduce wear and support longer service life in high temperature and severe service applications.

FAQ

1. What is a triple offset butterfly valve used for?

It is commonly used in steam, oil and gas, petrochemical, power generation and other industrial systems where high temperature, higher pressure and severe service conditions require a metal seated valve design.

2. What is the difference between a triple offset butterfly valve and a double offset butterfly valve?

A triple offset butterfly valve uses an additional geometric offset that creates a more refined sealing motion and is usually combined with a metal seat. This makes it more suitable for high temperature and severe service applications than a typical double offset butterfly valve.

3. Is this valve metal seated?

Yes. Triple offset butterfly valves are typically supplied with a metal seated sealing structure for high temperature and demanding industrial service.

4. Cette vanne peut-elle être fournie avec des actionneurs pneumatiques ou électriques ?

Yes. Worm gear, pneumatic and electric actuator configurations are available according to operating and control requirements.

5. Pour quels fluides cette vanne est-elle adaptée ?

It is generally suitable for steam, oil, gas, hot air, thermal oil and other industrial process media. Final material selection should be confirmed according to the actual working condition.

6. Can you provide customized materials, pressure classes or end connections?

Yes. Customized body materials, sealing structures, pressure ratings, end connections and actuation packages are available according to project requirements.
