The double eccentric butterfly valve adopts metall to metal seal, which further improves its high temperature resistance, high pressure resistance and corrosion resistance. It has a wide range of applications. such as petroleum, steam, paper pulp, chemicals, oxygen, ethylene, etc.

Features

The general butterfly valve has the disadvantage of lax sealing. In order to make up for this shortcoming, With the development of technology, the double eccentric butterfly valve came into being. The stem axis of the double eccentric butterfly valve is deviated from both the center of the butterfly plate and the center of the body. After the valve is opened, the butterfly plate can quickly separate from the valve seat, greatly eliminating unnecessary excessive extrusion between the butterfly plate and the valve seat, reducing the Increases opening resistance, reduces wear, and increases valve seat life.

Low maintenance. Double eccentric butterfly valve require minimal maintenance due to their durable construction and metal-to-metal seal, resulting in lower maintenance costs and reduced downtime.

Easy to operate and long service life. The control components such as the handle, gear and electric device of the double eccentric butterfly valve are all on the top of the valve, making it convenient for the operator to operate. In addition, the valve stem is connected to control components such as handles, gears and electric devices. This integrated structure can increase the service life of the valve and reduce maintenance costs.
