SMART IN FLOW CONTROL.

1Technology for The Future

From the idea to the fully fledged productHigh reliability and constant plant availability are notcontradictory where SAMSOMATIC solenoid valves
and limit switches are concerned. The intrinsicallysafe and flameproof versions have been added toour proven product line to provide a wide variety oftailor-made versions for any application.
The electropneumatic binary converter, which has
proven reliable in service a million times over, works
together with a pneumatic booster and forms theheart of the solenoid valves. Due to their minimal
power consumption, the solenoid valves can evenbe actuated using intrinsically safe fieldbus systems.
This efficient power usage also reduces the amountof self-generated heat and cuts cost for an emergency power supply.

The solenoid valves and limit switches are subjected
to high quality demands and are suiteable for use insafty-instrumented systems.
Different switching functions, flow rates, and connection types allow the devices to be tailor-made to meetall customer requirements.
