Product Introduction

The butterfly valve uses a PTFE-lined butterfly plate with a spherical sealing surface, and a silicone rubber gasket at the base of the valve seat to adjust the sealing performance of the valve; the valve is easy to operate, tightly sealed, and has a long service life; It can be used to quickly cut off or adjust the flow. It is suitable for occasions requiring reliable sealing and good adjustment characteristics.

The valve body adopts a split type, and the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat; so as to achieve compact structure, beautiful appearance, reasonable process and reliable performance.

Ensure that the valve shaft is not in contact with the fluid medium in the cavity. It is very convenient to replace the valve shaft. The valve can be completed without removing 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 WESDOM 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 WESDOM is very pleasant, and the products and services of WESDOM are also very considerate, and will have more cooperation with WESDOM valve in the future.
