PVDF 3 Way Ball Valve L-Port Type
A PVDF 3 Way Ball Valve L-Port Type is an industrial valve made from Polyvinylidene Fluoride (PVDF) that controls the flow of liquids or gases between three connected pipelines. A PVDF 3 Way Ball Valve L-Port is a chemically resistant plastic valve with three ports and an L-shaped internal passage that allows fluid to be diverted from one line to either of two other lines by rotating the valve handle. The L-port refers to the shape of the hole inside the ball. It is drilled in an “L” shape, allowing it to flow between Port 1 → Port 2 OR Port 1 → Port 3, but not both at the same time.
The PVDF 3 Way Ball Valve L-Port Type is a corrosion-resistant, multi-directional flow control valve designed for diverting applications in aggressive chemical and high-purity fluid systems. This valve ensures long-lasting performance in harsh environments. The L-port configuration enables fluid flow between two of the three ports, allowing for simple diversion or shut-off, making it ideal for applications in chemical processing, wastewater treatment, and semiconductor manufacturing.
