PVDF Butterfly Electrically Actuated Valve
A PVDF Butterfly Electrically Actuated Valve is a flow-control device that uses a butterfly valve mechanism made primarily from PVDF (Polyvinylidene Fluoride) material and is operated automatically by an electric actuator to control the flow of liquids or gases in a piping system. PVDF is resistant to acids, alkalis, and corrosive chemicals and rotates 90° to open or close the valve and to ensure tight sealing.
The PVDF Butterfly Electrically Actuated Valve is an advanced automated valve solution engineered for use in highly corrosive and chemically aggressive environments. Manufactured from high-purity Polyvinylidene Fluoride (PVDF), this valve offers excellent chemical resistance and durability. It is integrated with an electric actuator that enables precise remote operation and flow control, making it ideal for process automation in chemical plants, oil, gas treatment facilities, and high-purity fluid systems.
