Introduction to PTFE Butterfly Valves
A PTFE Butterfly Valve is a quarter-turn rotational motion valve designed to regulate, isolate, or control fluid flow in pipelines. It incorporates a PTFE (Polytetrafluoroethylene) liner or seat to provide exceptional chemical resistance, anti-corrosion performance, and high sealing integrity. These valves are ideal for applications involving corrosive chemicals, acids, alkalis, solvents, and high-purity media.
Industries dealing with aggressive fluids often require valves that can withstand extreme chemical exposure without degradation. PTFE lining offers unmatched resistance to most industrial chemicals, making these valves highly reliable in chemical process industries.
Common related valve types include:
PTFE Lined Butterfly Valve
Flanged Butterfly Valve
Wafer Type Butterfly Valve
Lug Type Butterfly Valve
Chemical Resistant Butterfly Valve
These variants are selected depending on pipeline design, pressure class, installation preference, and industry standards.
Design & Construction Details
1. Body Construction
The valve body is typically manufactured from Cast Iron (CI), Ductile Iron (DI), Carbon Steel (CS), or Stainless Steel (SS). The interior surface is lined with PTFE to ensure chemical resistance and smooth flow characteristics.
2. PTFE Lining
PTFE lining provides:
Superior chemical resistance
Low friction coefficient
Non-stick surface
High temperature tolerance
Excellent sealing capability
3. Disc Material
The disc can be manufactured in Stainless Steel (SS304, SS316, SS316L), WCB, or other alloy materials depending on media compatibility and pressure requirement.
4. Stem/Shaft
The shaft is precision machined for smooth quarter-turn operation and long operational life. Available in SS410, SS304, or SS316 materials.
5. End Connection Options
Wafer Type
Lug Type
Flanged Type
Working Principle
PTFE Butterfly Valves operate using a rotating disc mounted on a shaft. When the handle or actuator rotates the shaft by 90 degrees, the disc either allows flow (open position) or blocks flow (closed position). The PTFE seat ensures tight shut-off and prevents leakage even under corrosive conditions.
Because of its quarter-turn operation, the valve offers quick actuation and minimal torque requirement compared to other valve types such as gate or globe valves.
