PTFE Seated Butterfly Valve
PTFE Seated Butterfly Valve Manufacturer
MVS Valves is a trusted name in the manufacturing and export of PTFE Seated Butterfly Valve, delivering reliable sealing performance in highly corrosive flow applications. Engineered for precision control, these valves are widely preferred in chemical, pharmaceutical, and municipal water systems, where resistance to aggressive media and tight shut-off are essential. Our PTFE-seated butterfly valve design integrates a durable stainless steel disc stemmed through a resilient PTFE-lined seat, ensuring a long service life even under fluctuating pressure and temperature ranges. These valves are tested to API 598 and EN 12266 standards and designed as per API 609, making them suitable for demanding process conditions from –20 °C to +200 °C.
Built for compatibility and ease of automation, the valves come with an ISO 5211 actuation mounting pad and are available in both wafer and lug-style body configurations. MVS manufactures concentric PTFE-seated butterfly valve options with replaceable seat design, providing easy maintenance and superior resistance to wear and corrosion. These valves are available in PN 10 pressure rating and are offered in cast iron, ductile iron, carbon steel, and stainless steel body materials, including CF8 and CF8M grades. Whether installed in vertical or horizontal lines, each carbon steel PTFE seated butterfly valve or ductile iron PTFE seated butterfly valve provides bubble-tight sealing performance in applications involving vacuum, steam, acids, or process fluids.
The MVS product range includes stainless steel PTFE seated butterfly valve variants that offer a perfect blend of mechanical strength and chemical stability, particularly beneficial in pharmaceutical and clean utility systems. Every PTFE seat is carefully selected and designed to provide excellent resistance to chemical attack, ensuring minimal torque, smooth operation, and long-term performance. Being a reputed API 609 PTFE seated butterfly valve manufacturer and exporter, MVS Valves delivers quality solutions with a focus on performance, durability, and global compliance, making our valves the first choice for industries that demand corrosion resistance without compromise.
