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
