Technical data

T max 200 °C
DN max 600
PN max 10


Centred-disc butterfly valve with PFA liner for the chemical industry. With lever, manual gearbox, pneumatic or electric actuator. With wafer-type body (T1), full-lug body (T4) or U-section body with raised faces (T6). Connections to EN, ASME or JIS.


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 in combination with a stainless steel valve disc. Fluids requiring absolutely safe handling.
