Diaphragm valve SISTO-KB

with handwheelelectrically-actuatedfor control

Diaphragm valve to DIN/EN with flanged ends, in straight-way pattern; shut-off and sealing to atmosphere by diaphragm; hydraulically favourable full bore body with coating or lining, position indicator with integrated stem protection. From DN 125 with threaded bush. All moving parts are separated from the fluid by the diaphragm. Maintenance-free. Main Applications ■ - Food and beverage industry ■ - Industry, building services and power stations ■ - Chemical and process engineering ■ - Service water ■ - Air ■ - Oil ■ - Technical gases ■ - Abrasive and aggressive fluids Technical Data Function Shut off/control flow Connection type Flange Design concept Drive With electric actuator With handwheel With pneumatic actuator Casing material EN-GJL-250,EN-GJS-400-18-LT Nominal pressure PN 10 Max. nominal size DN 200 Min. nominal size DN 15 Max. allowed fluid temperature 140 °C Min. allowed fluid temperature -20 °C Benefits Reliable sealing to atmosphere and absolutely tight shut-off The diaphragm provides absolutely tight shut-off as well as hermetic sealing to atmosphere and of all operating elements. Low flow resistance coefficient Streamlined straight-through type body design Excellent resistance to corrosion and abrasion High-quality body materials and linings offer reliability + a long service life. The stem protection integrated in the position indicator prevents ingress of contaminants. Valve hydraulics without dead volume ensure optimum conditions for high-purity fluids + protection against deposits. Quick identification of valve position The stem and all internal operating elements are not in contact with the fluid.
