Introduction
Bi-offset Butterfly Valve, also known as high-performance butterfly valve, is a type of butterfly valve with optimized structural design. Its "double eccentricity" means that the rotation axis of the butterfly plate is offset by a distance relative to the center of the valve body and the center of the sealing surface. This structural design can effectively reduce the contact and friction of the sealing surface during opening or closing, and improve the sealing performance and service life.
Advantages
1. Strict material selection
The double eccentric butterfly valve fully considers the corrosiveness and strength requirements of different media and use environments in terms of material selection. The valve body can be made of a variety of materials such as carbon steel (WCB), stainless steel (CF8, CF8M), duplex steel (2205), nickel-based alloys (such as C276, Inconel 625), etc., to ensure the long-term stable operation of the valve in corrosive media such as acid and alkali, high temperature, high pressure, low temperature and seawater.
2. High-precision processing technology
Key components are processed by CNC equipment to ensure processing accuracy and consistency, especially the sealing parts, whose surface roughness can be controlled within the range of Ra0.2~0.4μm, thereby ensuring the fit and tightness of the sealing surface. This processing accuracy not only improves the sealing performance, but also reduces the opening and closing torque, which helps to extend the operating life of the valve and reduce the maintenance frequency.
3. Comprehensive surface anti-corrosion treatment
In order to adapt to the external corrosion effects of various harsh environments, the valve surface can choose different anti-corrosion treatment methods according to the use environment, such as epoxy resin spraying, anti-rust paint, PTFE spraying or rubber lining, etc. These treatment processes can effectively block the corrosion of the metal surface by external media, especially suitable for outdoor, humid, salt spray or chemical and other corrosive environments, extending the service life of the equipment.
4. Customized service
Size customization: A wide range of nominal diameters, from DN50 to DN2000 (2"~80"), can be provided, and special diameters can also be designed and manufactured according to specific needs;
Pressure level customization: Covers multiple standard pressure levels such as PN10~PN100 and ANSI Class 150~600, and structural reinforcement and strength analysis can be performed on demand;
Sealing material customization: According to the type of medium and temperature requirements, PTFE, EPDM, NBR, FKM, metal cladding alloy, Stellite alloy and other sealing material options are provided;
Connection method customization: Supports multiple connection forms such as flange, clamp, lug, welding, butt welding end, etc., which is convenient for use with different types of pipelines or equipment;
Drive device customization: The valve can be equipped with manual, electric, pneumatic, hydraulic or intelligent control actuators, which can realize local or remote automatic control and is suitable for different levels of automation systems.
