Potter osysu-1 gate valve supervisory switch
The OSYSU is used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve. The OSYSU-1, contains one set of SPDT (Form C) contacts. These switches mount conveniently to most OS&Y valves ranging in size from 2" to 12" (50mm to 300mm). They will mount on some valves as small as " (12,5mm).
The cover is held in place by two tamper resistant screws that require a special tool to remove. The tool is furnished with each device and should be left with the building owner or responsible party. Replacement or additional cover screws and hex keys are available. See Ordering Information.
