encapsulated diaphragm reduces
the flow incline of the elastomer and the risk
of a leakage by decrease of the diaphragm
General
eliminated water hammer
depending on the diaphragm
material for all neutral and aggressive, gaseous
and liquid media
the flow can be in either
direction
hermetic sealing
the valve is unaffected by
contaminated media
cavity free body
without any corrosion
Options
Available with a wide range of
control equipment and accessories, also for
retrofitting
Control connection in flow
direction
