PVDF Butterfly Valve LUG Type
A PVDF Butterfly Valve Lug Type is a quarter-turn flow control valve made from Polyvinylidene Fluoride (PVDF), designed with threaded lug inserts on both sides of the valve body that allow it to be bolted directly between two pipe flanges. The PVDF Butterfly Valve Lug Type uses a rotating disc mounted on a shaft. When the handle or actuator turns 90°, the disc either allows flow (open position) or blocks flow (closed position). The lug-type design allows for easy installation between flanges and provides the ability to isolate one side of the pipeline without disturbing the other. Ideal for applications in chemical processing, oil and gas treatment, and semiconductor industries.
The PVDF Butterfly Valve Lug Type is a durable, corrosion-resistant valve designed for efficient flow regulation and isolation in chemical and industrial piping systems. Made from high-quality Polyvinylidene Fluoride (PVDF), this valve delivers excellent chemical resistance and mechanical strength, making it suitable for aggressive media and harsh environments.
