POTTER OSYSU Series Outside Screw and Yoke Valve Supervisory
OSYSU Models
Potter has improved upon the already great OSYSU to make it even easier to install. It now contains visual indicators that show the status of the switch. The white visual indicator is visible through the window on the back of the switch actuator and helps guide the installer to ensure easy and precise installation. The mounting bracket is serrated to provide a more secure fit to the valve yoke. There is also an improved adjustment feature on the OSYSU that eliminates the need to loosen or remove the mounting hardware after initial installation in order to make fine adjustments.
