Potter Nitrogen Generators
Potter Nitrogen Generators are engineered to deliver up to 99% pure, reliable, dry Nitrogen to your system, protecting it from corrosion.
The OSYSU-CRH is used to monitor the open position of an OS&Y (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 OS&Y valves ranging in size from 2" to 12" (50mm to 300mm). They will mount on some valves as small as ½" (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.
