Fluorine-lined butterfly valves (featuring PTFE, PFA, or FEP linings) are designed specifically for handling toxic, highly corrosive chemical media, strong acids, and alkalis, providing complete chemical inertness and zero medium contamination.
Yes. The lining materials comply with FDA standards, making these valves suitable for processes with strict hygiene requirements, such as pharmaceutical and food-grade handling where non-contaminating properties are essential.
The valves can be operated through manual solutions including hand levers and gearboxes, or automated systems including pneumatic actuators and electric actuators fitted via an ISO 5211 upper flange standard.
Yes, these butterfly valves can be installed in any pipeline orientation and position. They are virtually maintenance-free and engineered to reliably perform under harsh, rigorous industrial conditions.
Sizes range from DN40 up to DN1200. Supported pressure ratings include PN10, PN16, Class 150, JIS 5K, and JIS 10K, conforming to international manufacturing standards such as API 609, BS 5155, DIN 3202, and ISO 5752.
