Potter OSYSU-CRH Corrosion Resistant OSandY Valve Supervisory Switch

About this product

Potter OSYSU-CRH is used to monitor the open position of an OSandY (outside screw and yoke) type gate valve in corrosive environments. The OSYSU-CRH provides additional corrosion protection on top of the NEMA 4X enclosure with corrosion resistant mounting hardware. These switches mount conveniently to most OSandY valves ranging in size from 2 Inch to 12 Inch (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.
