Rotary valves – butterfly valves

PN 16: standard valves VKF41

PN16 standard valve

Wafer type butterfly VKF41 valves DN 40 to DN 200 for mounting between PN 6, PN 10, PN 16 counter-flanges to ISO 7005; leakage rate less than 0.25% of kVS value; medium temperature: -10…120 °C

Suitable as shut-off valves in closed circuits in standard HVAC applications, e.g. boiler and chiller sequencing circuits, to open or close the flow to a heat exchanger or to complete plant sections.

PN 16: high performance valves VKF46 with tight shut-off

PN16 high performance valve

Wafer type butterfly VKF46 valves: DN 40 to DN 400 for mounting between PN 6, PN 10, PN 16 counter-flanges to ISO 7005; DN450 to DN600 for mounting between PN16 counter-flanges to ISO 7005; tight-closing in accordance with EN 12266-1, leakage rate A (air bubble tight) medium temperature: -10…120 °C .

VKF46TS high close-off pressure valves differ in the materials used and in the continuous end to end shaft through the associated disc.

Suitable as shut-off valve in open and closed circuits in standard HVAC applications, e.g. boiler, chiller and cooling tower sequencing circuits, to open or close the flow to a heat exchanger or to complete plant sections.
