Barksdale Sealed Piston Switches

9617 Series Sealed Piston Models

The 9617 Series features a unique leaf spring design to reduce the number of moving parts. These units provide higher reliability and a longer life than other sealed piston type pressure switches; millions of maintenance-free cycles are assured. They are ideal for use where pulsations exceed 25 cycles/minute or where high over-pressure can occur; proof pressure is to 15,000 psi.

Series switches are housed in a watertight, die-cast aluminum enclosure with Lexan cover. Wetted materials are brass, stainless steel and Buna N. Internal indicator makes set point calibration quick and easy.
