PTFE/PFA Lined Split Butterfly Valve
The PTFE/PFA lined split butterfly valve is designed for industrial pipeline systems handling corrosive fluids, chemicals, and other demanding process media. With a corrosion-resistant lining and specialized split shaft structure, this valve provides reliable flow control, effective sealing, and convenient maintenance.
The valve features a lined butterfly plate and sealing components designed to reduce direct contact between the process medium and the metal valve body. It is suitable for applications requiring corrosion resistance, contamination control, and dependable operation.
Available with pneumatic, electric, hydraulic, or manual operating configurations according to project requirements.

Main Features of PTFE/PFA Lined Split Butterfly Valve
1. Excellent Corrosion Resistance
The PTFE/PFA lined design provides excellent resistance to many corrosive chemicals and aggressive process media. It helps protect the valve's internal flow-contact surfaces and supports reliable operation in chemical processing environments.
2. Reliable Shaft Sealing Structure
The shaft sealing structure uses O-rings, elastic isolation bushings, and butterfly springs. This design helps prevent process media from entering critical sealing areas and provides automatic compensation for sealing performance.
3. Split Disc and Shaft Design
The butterfly disc adopts a split construction, while the valve shaft features a special-shaped connection. This structure facilitates assembly, inspection, maintenance, and replacement of relevant components.
4. Replaceable Valve Seat
The replaceable valve seat design makes maintenance and servicing more convenient. It helps reduce maintenance difficulty and supports longer service life when properly selected and operated.
5. Flexible Actuator Compatibility
The valve is equipped with an ISO standard actuator mounting plate, allowing connection to pneumatic, electric, hydraulic, and other compatible actuators for automated pipeline control.
Working Principle
The PTFE/PFA lined split butterfly valve controls pipeline flow through the rotation of its butterfly disc. When the actuator drives the valve stem, the disc rotates around its shaft.
When the disc is parallel to the flow direction, the valve opens and allows the medium to pass through. When the disc rotates approximately 90 degrees to the closed position, it contacts the valve seat and restricts or shuts off the flow.
The PTFE/PFA lining and specialized sealing structure provide protection against corrosive media and support reliable sealing performance.
Industrial Applications
The PTFE/PFA lined split butterfly valve is suitable for industrial processes where corrosion resistance, material compatibility, and reliable flow control are important.
Chemical Processing Industry
Used in chemical transfer pipelines, acid and alkali handling systems, and corrosive liquid transportation where compatible PTFE/PFA lining is required.
Petrochemical Industry
Applied in selected petrochemical process pipelines for controlling compatible oil, gas, and chemical media.
Pharmaceutical Industry
Suitable for selected process pipelines requiring corrosion-resistant materials and reduced risk of medium contamination, subject to applicable cleanliness requirements.

Frequently Asked Questions
1. What is a PTFE/PFA lined split butterfly valve?
It is a center-line butterfly valve with PTFE or PFA lining designed for controlling corrosive and chemically aggressive media in industrial pipelines.
2. What is the difference between PTFE and PFA lining?
PTFE and PFA are fluoropolymer materials offering excellent chemical resistance. Their mechanical, processing, and temperature characteristics differ. The suitable material should be selected according to the medium, operating temperature, and pressure.
3. What materials are available for the valve body?
Available body material options include ductile iron, CF8, CF8M, and WCB, depending on the valve design and operating conditions.
4. Can this butterfly valve be equipped with an actuator?
Yes. The valve can be configured with compatible pneumatic, electric, or hydraulic actuators.
5. What media can this valve handle?
It can be used for compatible water, oil, gas, and corrosive media. Actual suitability depends on chemical concentration, temperature, pressure, and material compatibility.
6. Is the valve seat replaceable?
Yes. The replaceable seat design facilitates inspection, maintenance, and replacement.
