Stainless Products’ micro/proximity switch valves have the same great features as the other valves in our line. In addition, Stainless Products uses environment-proof switches. A precision basic switch is located in a corrosion resistant 316L housing to protect the switch contacts from contamination.
The switch(es) can indicate by light or readout on a control panel whether the valve is in the full-open or full-closed position. The micro/proximity switch actuator can be used on any Stainless Products air valve. For details please contact us.
