Lined Butterfly Valves

Lined butterfly valves are a specialized type of valve designed for controlling the flow of fluids within a system. These valves feature a unique construction that combines the versatility of a butterfly valve with the protective benefits of a lining material.

Key characteristics and features of lined butterfly valves include:

Versatile Flow Control: Lined butterfly valves are well-suited for a wide range of applications, including industries such as chemical processing, water treatment, pharmaceuticals, and more. They can handle various types of fluids, from corrosive chemicals to abrasive slurries.

Corrosion Resistance: The primary advantage of lined butterfly valves is their ability to resist corrosion. The lining material, often made of materials like PTFE (polytetrafluoroethylene), PVDF (polyvinylidene fluoride), or rubber, creates a barrier between the fluid and the valve's internal components, preventing corrosion and degradation.

Abrasion Protection: In addition to corrosion resistance, the lining also provides protection against abrasion caused by the flow of particulates or abrasive materials within the fluid.

Biocompatibility: Lined butterfly valves with appropriate lining materials are suitable for use in industries that require biocompatibility, such as food and pharmaceuticals.

Reduced Maintenance: The use of lining materials reduces the need for frequent maintenance and replacement of valve components due to corrosion or abrasion, resulting in cost savings and extended service life.

Tight Shutoff: Lined butterfly valves offer good sealing capabilities, providing tight shutoff when closed. This is crucial for preventing leaks and maintaining process integrity.

Lightweight Design: The butterfly valve's design, characterized by a disc that rotates around a central shaft, makes it inherently lightweight. This design minimizes the overall weight of the valve, making it easier to install and operate.

Quick Operation: Lined butterfly valves can be operated quickly, making them suitable for applications where rapid opening and closing are required.

Cost-Effective Solution: Compared to some other types of valves, lined butterfly valves can offer a cost-effective solution for fluid control, especially in corrosive or abrasive environments.

Automation Compatibility: Lined butterfly valves can be integrated into automated systems, allowing for remote control and precise adjustments based on process conditions.
