APV SV/SVS Series Butterfly Valves

APV Butterfly Valves: SV1 and SVS1F Series

Core Advantages

• One actuator covers all diameters from 1″ (25 mm) – 4″ (100 mm).
• Slide bearings on the pivots of the discs increase operating reliability.
• Visual indication of open/closed position.
• SVS1F intermediate flange design allows simple removal and easy access of valves that are in lengthy or fixed pipelines.
• ATEX compliant models
• Designs with electro-pneumatic control (flow control) with Bürkert positioner
