STAINLESS STEEL Triple Offset Flanged PTFE Seat Ring Butterfly Valve

The stainless steel triple offset flanged PTFE seat ring butterfly valve operates using a disc designed with three geometric offsets between the shaft, disc, and seat. During opening, the disc rotates away from the PTFE seat without sliding contact, reducing friction and wear. When closing, the disc gradually approaches the seat and achieves full sealing only at the final position. This design ensures tight shutoff, even under high pressure or temperature conditions. The flanged connection provides secure installation and accurate alignment in pipelines. The PTFE seat ring offers excellent chemical resistance and low torque operation, making the valve suitable for demanding industrial and corrosive fluid applications

Valve parts

• The triple offset design eliminates disc-to-seat friction during operation, significantly reducing wear, extending service life, and ensuring reliable sealing performance under frequent opening and closing conditions.
• The PTFE seat ring provides excellent chemical resistance, low friction, and tight shutoff, making the valve suitable for corrosive media and demanding industrial process environments.
• Stainless steel construction offers high mechanical strength, corrosion resistance, and long-term durability, supporting use in high-pressure, high-temperature, and harsh operating conditions.
• The flanged connection ensures secure installation, accurate alignment, and stable sealing, making the valve reliable for large-diameter pipelines and critical flow control systems.

Sanitary Butterfly valve widely use in low and medium viscosity liquid for food and beverage, beer, dairy, pharmaceutical etc with high precision and purity requirements industries.
