Butterfly Valve has existed for a long time and has a wide range of applications. They first appeared in the 1930s and have been used by many industries since then. Butterfly Valves are usually made of cast iron, and the name comes from the functionality of the disc.
Multi standard soft seat butterfly valve with gear operator is manufactured with an epoxy-coated cast iron body for high strength and corrosion resistance. A standard ductile iron disk, with aluminum bronze or stainless steel available upon request.
This product is ideal for throttling or shutting off the flow of gases, liquids, semi-liquids, and even solid powder. The body design is such that it can be used with most international flanges, including AS2129, BS10, ANSI, DIN, and JIS. The Wafer Type is designed for inline service and relies on a flange on either side of the valve to secure the pipeline.

Project Name: A valve dealer in Pakistan imports valves as inventory for sale.
Main Products: American standard gate valves, stainless steel check valves, ductile iron soft-sealed gate valves, wafer butterfly valves, exhaust valves and other valves.
This valve distributor from Pakistan described some informations about their company to our sales manager of the international department.They have been engaged in the valve industry for 11 years and are very professional, with a fixed customer base and sales methods. As a middleman, they need to purchase a large number of valves that are sold every day. And China is a big valve producing country, so they intend to cooperate with Chinese valve manufacturers as their own exporter. After some comparisons, the enthusiasm form WEIZIDOM left a deep impression on them. From the initial samples, trial orders to subsequent FCL orders, the cooperation is very smooth and pleasant. This Pakistan distributor said that the cooperation with WEIZIDOM is very pleasant, and the products and services of WEIZIDOM are also very considerate, and will have more cooperation with WEIZIDOM valve in the future.
