\u042d\u0442\u043e\u0442 PFA\/PTFE Fully Lined Butterfly Valve<\/strong> is specifically engineered for ultra-high purity and highly corrosive fluid control applications. By combining a high-strength SCS13 duplex stainless steel valve body<\/strong> with a 100% full plastic lining<\/strong>, the valve delivers exceptional corrosion resistance, long-term sealing reliability, and contamination-free performance in the most demanding industrial environments.<\/p>\n

Ultra-High Purity & Outstanding Corrosion Resistance<\/h2>\n

The valve features a fully encapsulated PFA lining<\/strong> covering the valve body cavity, disc, and stem, completely isolating metal parts from the process media. This design effectively eliminates metal ion leaching and ensures compliance with stringent purity requirements, making it ideal for semiconductor, photovoltaic, pharmaceutical, and specialty chemical processes.<\/p>\n

\u041e\u043d PFA\/PTFE composite sealing surface<\/strong> provides outstanding chemical inertness and temperature resistance, achieving bubble-tight, zero-leakage performance even under aggressive chemical exposure.<\/p>\n

Robust Structure & Reliable Sealing Performance<\/h2>\n

Structurally, the SCS13 cast duplex stainless steel body<\/strong> offers superior mechanical strength and excellent resistance to stress corrosion cracking compared to conventional stainless steels. This ensures stable operation under pressure while extending the valve\u2019s service life.<\/p>\n

The smooth, fully lined flow passage minimizes pressure loss, reduces fluid residue, and prevents contamination buildup, supporting both process efficiency and cleanliness.<\/p>\n

Designed for Harsh Operating Environments<\/h2>\n

Designed with safety and usability in mind, the valve is equipped with a corrosion-resistant plastic handle<\/strong> that provides thermal insulation and reliable operation in harsh chemical environments.<\/p>\n

Depending on the selected lining material, the valve can operate across a wide temperature range, making it adaptable to various process conditions. The lightweight construction further improves operational safety and handling convenience.<\/p>\n

Easy Installation & Low Maintenance<\/h2>\n

The valve adopts a wafer-type connection<\/strong>, allowing for quick installation with minimal space requirements. Its lightweight design simplifies handling, while the fully lined internal structure reduces maintenance frequency and lowers long-term operating costs.<\/p>\n

Typical Applications<\/h2>\n

This butterfly valve is widely used in applications where purity, safety, and corrosion resistance are critical, including:<\/p>\n
