Vannes papillon concentriques à double bride:
Les vannes papillon concentriques à double bride se caractérisent par leur construction robuste et leurs capacités de contrôle précis du débit.. Ces vannes comportent deux brides, un de chaque côté du corps de vanne, which facilitate easy connection to piping systems. The concentric design ensures that the valve’s disc is perfectly centered within the valve body, enabling efficient and reliable flow regulation. Our double flange concentric butterfly valves are available in a range of sizes, from DN50 to DN400, and can withstand pressure ratings of up to Pn1.0～1.6mpa.
Our double flange concentric butterfly valves are meticulously engineered to meet the highest standards of performance and durability. Here are the key parameters that define their exceptional quality:
1. Écart de température: These valves can operate effectively within a temperature range of -10℃～150℃, catering to a wide spectrum of industrial applications.
2. Pressions nominales: With pressure ratings of Pn1.0～1.6mpa, our valves are suitable for various medium-pressure systems.
3. Gamme de taille: The availability of sizes from DN50 to DN400 ensures compatibility with different pipe diameters.
4. Type de connexion: The flanged connection type simplifies installation and provides a secure connection to piping systems.
5. Norme de connexion: Our valves comply with multiple international standards, including GB, ANSI, DEPUIS, API, OIN, et BS, ensuring global compatibility.
6. Durée de vie des vannes: The robust construction and high-quality materials used in our valves guarantee a long service life of up to 50 années.
7. Matériaux du corps: We offer valves with cast iron or ductile iron bodies, providing options for different strength and corrosion resistance requirements.
8. Matériau du siège de soupape: The rubber valve seat ensures a tight seal and minimizes leakage.
9. Matériau de la plaque de soupape: The valve plate can be made of stainless steel or ductile iron, depending on the specific application requirements.

Connecting Butterfly Valve Flange:
Connecting a butterfly valve flange involves several steps to ensure a secure and leak-free installation:
1. Preparation: Ensure that the valve and piping flanges are clean, free from debris, and properly aligned.
2. Gasket Placement: Place the gasket between the valve flange and the piping flange, ensuring proper alignment and seating.
3. Bolt Installation: Insert the bolts through the flange holes and hand-tighten the nuts.
4. Tightening: Gradually tighten the nuts in a crisscross pattern to evenly distribute the load and create a uniform seal.
5. Final Inspection: Double-check all connections and ensure that the valve is securely fastened to the piping system.
Features of Butterfly Valve Flange End:
Le butterfly valve flange end plays a crucial role in ensuring a secure connection between the valve and the piping system. Here are some key features of butterfly valve flange ends:
1. Flange Standards: Butterfly valve flanges adhere to various international standards, such as ANSI, DEPUIS, and JIS, ensuring compatibility with different piping systems.
2. Pressions nominales: Flange ends are designed to withstand specific pressure ratings, catering to different application requirements.
3. Matériaux: Flange end materials can vary, including carbon steel, acier inoxydable, and alloy steel, to suit different temperature, pressure, and corrosion resistance requirements.
4. Gasket Compatibility: Flange ends are designed to accommodate specific gasket types, such as rubber, metal, or composite gaskets, to ensure a proper seal.
