Kieselmann 5671 Double-seat Valve With Shaft Flushing

BRAND : Kieselmann

Contamination-free separation

KIESELMANN double-seat valves are the first choice to safely separate in automatic process equipment, which does not belong together.

Our double-seat valves are among the most modern, safest valves on the market. Two independently controllable valve plates with non-pressurised leakage discharge prevent incompatible media from mixing. Product rearward migrations of the valve disk seals are excluded. If a leak occurs contrary to expectations, the medium flows out through the leakage gap without pressure.

Split valve plates for maximum safety.

The easy cleaning of the leakage space is performed by lifting the upper or lowering the lower valve plate.

Everything under control thanks to comprehensive automation optionsfrom sensor monitoring via PLC or ASI-BUS control head through to emergency stop function and valve position indication. An ATEX version is even available for gas and dust areas (Zones 1, 2 and 21, 22).
