Electric PTFE-lined butterfly valve – a suitable choice for highly corrosive working conditions

In chemical, new energy, and environmental process industries, the management of corrosive media has always been a major challenge. When strong acids, strong alkalis, or strong oxidizing media flow through pipelines, the reliability of valves directly determines the safety and continuity of the entire system.

Electric PTFE-lined butterfly valves not only solve the corrosion resistance problem in highly corrosive environments but also redefine the standard for high-end fluid control through intelligent control and high-precision adjustment.

PTFE-lined for corrosion resistance, fearless against strong corrosion

Ordinary metal valves often struggle to withstand highly corrosive media such as sulfuric acid and hydrofluoric acid.

Electric PTFE-lined butterfly valves use WCB carbon steel as the pressure-bearing body to ensure mechanical strength; the valve body, butterfly plate, and valve seat, which come into contact with the media, are all lined with fluoroplastics (PTFE, FEP, or PFA). This "strong on the outside, tough on the inside" design can resist the erosion of almost all strong acids, strong alkalis, organic solvents, and strong oxidizers.

A wide temperature range of -20℃ to 150℃ allows it to easily handle most corrosive chemical conditions.

Precise Control, Intelligent Linkage

This butterfly valve is equipped with a high-precision electric actuator, pushing regulation performance to new heights.

Ultimate Precision: Opening adjustment accuracy reaches ±1%~±2%, with a resolution as low as 0.1°~1°, meeting precise mixing requirements.

Intelligent Connectivity: Supports wired (Modbus RTU/TCP) and wireless (5G, LoRa) communication, enabling seamless linkage with PLC and DCS systems for remote control, timed control, and unattended operation.

Lightweight Design, Space Saving

In space-constrained technical upgrade projects or compact equipment, installation space is often a precious resource.

The electric PTFE-lined butterfly valve is small and lightweight, weighing only about 1/3 of a PTFE-lined gate valve of the same diameter, making it particularly suitable for installation in pipe wells, equipment mezzanines, or skid-mounted equipment, significantly reducing the load on pipe supports.

Clean and Purity-Safeguarding

In the pharmaceutical and high-purity chemical industries, the electric PTFE-lined butterfly valve offers a higher level of value—ensuring the purity of the media.

Fluoroplastic linings offer superior purity and prevent impurity leaching. In the pharmaceutical industry, they are used in acid and alkali cleaning solution pipelines and for transporting intermediate pharmaceutical solutions, meeting GMP standards and preventing metal ion contamination. Combined with intelligent control, they enable precise proportioning and automated production processes.

From the robust barrier of fluoropolymer lining against corrosion to the intelligent adjustment of precise control; from the innovative lightweight design to the protection of pristine quality—the electric fluoropolymer-lined butterfly valve is a key execution unit for achieving intelligent and green production in the process industry.
