1540 Side Mounted Pneumatic Level Switch

The 1540 is a horizontally mounted, float operated level switch suitable for plant and OEM applications where pneumatic valve operation is required to signal presence or absence of liquid at a discrete level. 

The float arm moves a magnet which in turn moves a shuttle that either blocks or allows pilot pressure to pass and operate ancillary equipment.

Actuation (deactuation) can be reversed by rotating the unit 180 degrees or switching inlet connections.
