About Butterfly Valves
Butterfly valves are used in pipelines to regulate the flow, such as shut-off flow. Because butterfly valves have many advantages, such as closing faster than gate valves, small installation space, two-way use, zero leakage, and maintenance-free, they are widely used in various industrial processes such as water treatment systems, ships, power plants, and fine chemicals.
Usually, butterfly valves can be divided into concentric butterfly valves, double-offset butterfly valves, and triple-offset butterfly valves according to the structure. Among them, the triple offset butterfly valve is resistant to high temperature and high pressure due to its metallic seal, and the triple offset structure solves the leakage problem, and truly achieves absolute zero leakage, making it widely used in oil and gas exploration and processing, oil refining and petrochemical equipment, power plants, and steel plants.
Butterfly Valves By Features
There are centerline butterfly valves, double-offset butterfly valves, and triple-offset butterfly valves for your choice.
Concentric butterfly valves are widely used in water processing and treatment, food and beverage, swimming pool installation, heating, natural gas, etc.
Be designed for operation in very hard industrial conditions, such as the power industry, crude oil, and natural gas, refineries, etc.
Be used in hard industrial conditions, for example, the nuclear energy industry, chemical industry, shipbuilding, etc.
Product Feature Box
Soft sealed and offset structure assures good sealing performance.
The offset structure can reduce a lot of friction and prolong the service life.
Two-way sealing and two-way pressure bearing assure the two-way flow.
Butterfly valve is a good choice if the installation space is insufficient.

Butterfly Valve in Special Alloy Materials
In order to better cope with harsh environments and corrosive media, alloy materials with stronger corrosion resistance are increasingly used in valve manufacturing.
Nickel Aluminum Bronze Large Butterfly Valves are especially suited for low-pressure seawater applications. We recommend nickel-aluminum bronze for the valve body and Monel for internal parts, which is more economical.
Butterfly Valves In Different Projects
Because the internal medium of the valve is seawater, there are strict requirements on the valve body material, sealing material, and paint.
Because of the severe operational conditions, the applied valves should comply with certain certifications to assure safety. For this project, the owner requires Norsok certificate for valves.
