VOCESTER – Sanitary Butterfly Valve

This type of valve can be operated remotely via an electric or pneumatic actuator, or manually via a handle. The electric actuator or pneumatic actuator is to convert the axial movement of a piston into the 90° rotation of the valve shait, so as to realize the control of the pipeline fluid and the opening/closing task. There are three standards for pneumatic actuators: (NO) type, normally closed (NC) type, air/air, NA) type. The multi-position handle for duckbill manual operation can mechanically lock the valve on its 12 positions of opening or closing by adjusting the position of 15°, so as to achieve the purpose of controlling the medium flow: the lever type manual operation handle uses 4 multi-function Positioning, the valve is mechanically fixed on its open or closed 4 positions, which also achieves the purpose of controlling the flow of the medium.
