PTFE Lined Gate Valve

MVS Valves PTFE Lined Gate Valve is specifically engineered to handle highly corrosive, abrasive, and fiber-laden media found in chemical, pharmaceutical, and industrial process systems. Designed to ensure full bore flow and tight shut-off, this valve is available in both rising stem and non-rising stem configurations to suit different installation needs. In the rising stem model, the stem moves vertically along with the disc, allowing clear visual indication of valve position. In contrast, the non-rising stem design operates by rotating the stem without vertical movement, which is ideal for confined spaces.

To ensure unmatched corrosion resistance and reliable sealing, MVS offers PFA lined gate valves, FEP lined gate valves, and PTFE lined gate valves with high-integrity linings that withstand aggressive acids, alkalis, and solvents. These linings are permanently bonded to robust cast iron, carbon steel, or stainless steel bodies, delivering long-lasting protection and mechanical stability. The valve’s design ensures smooth operation and prevents clogging, especially when handling particulate-rich or viscous media, which can often lead to jamming in conventional gate valves.

Built to comply with global quality standards, our fluoropolymer lined gate valve range provides excellent resistance to a wide range of chemicals and temperatures. These valves are ideal for use in demanding environments like fertilizer plants, chlorine processing units, wastewater treatment, and specialty chemical industries. Each fluoroplastic lined gate valve is tested to ensure zero leakage and reliable operation under fluctuating pressure conditions.

As a trusted OS&Y type lined gate valve manufacturer, MVS focuses on providing valves that not only deliver high performance but also offer operational ease and maintenance-free longevity. Our fluorine lined gate valve models are widely preferred for their superior anti-stick surface, which prevents media buildup and ensures consistent flow. For industries requiring the highest standards of chemical resistance, we also offer fluorocarbon resin lined gate valves that provide exceptional thermal and pressure stability. Whether installed horizontally or vertically, our PTFE lined gate valves maintain full functionality with minimal torque, ensuring hassle-free operation in even the most aggressive process conditions.
