PVDF 3 Way Ball Valve T-Port Type

A PVDF 3 Way Ball Valve T-Port Type is a chemically resistant plastic valve made from Polyvinylidene Fluoride (PVDF) that allows fluid to flow between three connected pipeline ports. The “T port” refers to the internal bore of the ball, which is shaped like the letter T, enabling multiple flow path configurations. The PVDF 3 Way Ball Valve T-Port Type is a high-performance multi-directional flow control valve designed for use in corrosive and high-purity fluid systems. This PVDF 3 Way Ball Valve T-Port Type offers excellent chemical resistance and thermal stability.

The T-port design allows for various flow configurations, such as mixing or diverting, making it ideal for complex fluid handling in chemical processing, oil, gas treatment, and pharmaceutical applications. The T-port design allows mixing the two inlet flows into one outlet and diverting one inlet flow to two outlets for shut-off or selective directional control. By rotating the ball (usually 90° or 180°), the valve changes the flow path. A PVDF 3 Way Ball Valve T-Port Type is a corrosion-resistant thermoplastic valve with three ports and a T-shaped internal ball that allows mixing, diverting, or directing fluid flow within a piping system.
