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 Valve in Special Alloy Materials

NAB C95800 Butterfly Valves
Custom C95800 Butterfly Valves

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.

Petrobras Drilling Ship Project
Petrobras Drilling Ship Project

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.

What is Triple Offset Butterfly Valve?

The rotating shaft of the disc is offset from the center line of the disc seat and body seal (first offset) and the pipe’s center line (second offset). With triple offset process valves, the seat axis of rotation is also asymmetrically disposed to the pipe axis.

What is Hatelloy?

Hastelloy is a nickel-molybdenum alloy. It contains ultra-low carbon and high Ni, Mo, and Cr elements, which belong to corrosion-resistant and high temperature-resistant materials.
