Design
Centered disc butterfly valve with PFA liner. With lever, manual gearbox, pneumatic, electric actuator. Wafer type body (T1), full-lug type body (T4) or U-section body with raised faces (T6). EN, ASME, JIS connections possible.
Application
Highly corrosive fluids: toxic and highly corrosive fluids which cannot be handled by metals or elastomers, thus requiring the sole use of PFA. Moderately corrosive and aggressive fluids allowing the use of a PFA liner with a stainless steel valve disc. Fluids requiring absolutely safe handling.
