Product Details

    Duplex Eccentric Butterfly Valve have a short circular body, disc, metal-to-metal or soft seat, top and bottom shaft bearings, and stuffing box. For quality duplex stainless steel butterfly valves, we are one of the most trusted and reliable suppliers in China. We are the most important source of Chinese butterfly valve manufacturers , suppliers and exporters. The butterfly valve is a quarter-turn rotary motion valve that is used to stop, regulate and start flow.

    The Duplex Eccentric Butterfly Valve is easy to open. In this design, the 90° rotation of the handle provides complete closure or opening of the valve. We manufacture and supply large butterfly valves that are usually equipped with gearboxes that are connected to the valve stem by handwheels. This simplifies the operation of the valve, but at the cost of a gradual slowdown.

Typical application of Duplex Eccentric Butterfly Valve

    We are producing duplex eccentric butterfly valve that can be used in many different fluid services and perform well in slurry applications. The following are some typical applications for duplex eccentric butterfly valve

1. High stress corrosion and corrosion applications.
2. High pitting and crevice corrosion applications.
3. Stress corrosion cracking in chloride environment applications
4.Slurry and similar service applications
5. Vacuum service application
6. High pressure and high temperature steam applications                                                                         Advantages of duplex eccentric butterfly valve                                                                                                    
1.It is light in weight
2.It is quick to operate, and the time required to open or close the flow is shorter.
3. We can produce very large size of it.
4. enjoys low pressure drop and high pressure recovery characteristics.
6. Maintenance costs for duplex eccentric butterfly valves are generally lower due to the minimum number of moving parts and no grooves to trap fluid.
5.Duplex eccentric butterfly valve has many advantages than gate valve, ball valve, spool and ball valve, especially suitable for large valve applications.
