Value PFA/PTFE Lined Butterfly Valve – Superior Corrosion Resistance for Chemical Applications

The Value PFA/PTFE lined butterfly valve is specially designed for highly corrosive media such as acids, alkalis, solvents, seawater, and aggressive industrial fluids. With a full PTFE/PFA lining structure, the valve completely isolates the body from the process media, significantly improving durability and service life.

This valve is an ideal solution for:

• chemical plants
• petrochemical plants
• power plants
• pulp and paper mills
• nuclear facilities
• industrial water treatment systems

Key Features of Value PFA/PTFE Lined Butterfly Valve

Full PTFE/PFA Lining for Superior Corrosion Protection

The valve is designed with:

• two-piece wafer body
• concentric disc and seat structure
• full PTFE/PFA lining on body and seat

The PTFE/PFA lining thickness of 3–4 mm provides:

• complete isolation between body and media
• excellent resistance to chemical corrosion
• reduced scaling and deposits
• extended valve service life

Optimized Seat Design – Lower Operating Torque

The specially engineered seat geometry:

• reduces friction during opening and closing
• lowers operating torque
• minimizes wear on seat and disc

This allows smoother operation and longer sealing performance.

Top Stem Bushing for Smooth Shaft Operation

The top stem bushing:

• ensures proper alignment between upper and lower shafts
• reduces vibration and shaft play
• provides smooth and stable shaft movement

Disc Spring for Enhanced Sealing

The disc spring design:

• applies elastic force to compress the O-ring and seat
• improves axial sealing performance
• compensates for the lower elasticity of PTFE seat material

This ensures reliable sealing over long-term operation.
