The Sanborn 034-0134 pressure switch with unloader is a compact control device designed to regulate a system at a 95–125 psi operating range, featuring on/off contacts to automatically start and stop the connected equipment. It includes an unloader valve that releases residual pressure when the system shuts down, easing restarts and reducing startup load. Also cataloged as 0340134, this model combines unloader functionality with an on/off switch in a single assembly for installations requiring a 95–125 psi switch.
