PVDF Solenoid Valve 3/2 Way
A PVDF 3/2 Way Solenoid Valve is an electrically operated valve made from PVDF (Polyvinylidene Fluoride) that controls the flow of fluids in a piping system using three ports and two positions. A PVDF 3/2 Way” refers to 3 ports: inlet, outlet, and exhaust/return and 2 positions: open and closed (actuated or de-energized). The solenoid coil converts electrical energy into mechanical motion, moving a plunger to open, close, or divert the flow.
The PVDF Solenoid Valve 3/2 Way is an electrically operated valve designed for precise control of fluid flow in complex piping systems. It provides excellent chemical resistance and durability for handling aggressive and high-purity fluids. The 3/2 way configuration features three ports and two switching positions, allowing for versatile control functions such as diverting, mixing, or venting. This valve is widely used in chemical processing, pharmaceutical manufacturing, oil and gas treatment, and semiconductor industries where automated and reliable fluid control is essential.
