Cardinal valves

To perform reliably under extreme operating conditions, the Cardinal valves are rated for temperatures ranging from –40°C (–40°F) to 100°C (212°F). All parts are made from non-corrosive or a suitably protected material to withstand outdoor exposure on external surfaces and hot transformer oil on internal surfaces. Cardinal valves are robust in design, so that over-tightening or minor abuse encountered in handling or during factory/field installation will not result in valve malfunction. The fasteners are designed to prevent loosening under normal operating conditions. The operating handle displays the valve’s open and shut position and can be manually locked in either position. Cardinal valves are designed for use on new transformers or as replacements on existing electrical transformers. Cardinal valves are available in sizes ranging from 2 in. to 8 in., including ANSI standard and OEM-specific flange configurations
