❓ Frequently Asked Questions (FAQ)
► What working media are suitable for this full-lined lug butterfly valve?
This fully lined valve is specially engineered for handling toxic, harsh, and highly corrosive chemical media. Because the disc and body are insulated with robust PTFE liners, aggressive fluids are kept completely isolated from metallic components.
► Does this valve comply with sanitary and food-grade standards?
Yes, the lining and seating materials comply with FDA standards, making the valve suitable for high-purity chemical processes, pharmaceuticals, and food-related industries where cross-contamination must be prevented.
► Can the valve be installed in vertical or horizontal orientations?
Yes, the valve features a compact, bi-directional sealing design that can be installed in any orientation or position along the pipeline without compromising its maintenance-free operation or sealing integrity.
► What actuation options are compatible with the upper flange?
The top mounting pad conforms to the standard ISO 5211 interface, allowing direct and effortless integration with manual hand levers, worm gearboxes, electric actuators, and pneumatic actuators.
► How does the split body design benefit ongoing operations?
The removable split body structure allows for straightforward internal inspections, rapid liner/seat replacements, and easy separation of metals and fluoropolymers for eco-friendly recycling at end-of-life.
► What flange standards are supported by this lug-type body?
The lug body supports diverse connection standards including ANSI/ASME Class 150, EN/DIN PN6, PN10, PN16, PN25, JIS 5K, 10K, 16K, as well as GOST 33259 standards from sizes DN40 to DN1200.
