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
options from 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).
