APV Butterfly Valves: SV1 and SVS1F Series

Core Advantages

Product passages are smooth and the special seals ensure thorough cleaning.
Unique metallic stop prevents the valve flanges from being tightened too much and protects the valve seal from mechanical over-stress thus improving seal lifetime.
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
