APV / SPX Delta SV1 & SVS1F | Daken Stainless Products

APV / SPX Butterfly Delta SV1 & SVS1F
Smooth product passages and special seals ensure thorough cleaning. Metallic stop protects the valve flanges against over tightening and the valve seal against mechanical overstress, improving seal lifetime. One actuator covers all diameters from DN25/1” to DN100/4”. Slide bearings on the pivots of the discs increase operating reliability.
