There are several installation notes for butterfly valve .1.Before the installation should check the valve specifications, pressure, temperature, and corrosion resistant whether meets the use requirem

a butterfly valve actuator controls the flow of gas or liquid by means of a disk

A modular butterfly valve includes a disc member which is selectively rotated between an open and a closed position, a housing, a resilient valve seat, and a clamping ring which are held together by a

In the food industry, the cleanness of the pipes through which liquid food (milk, creams, etc.) flows is of great importance.
