Jordan Valve - Model Mark 80 Series -Self-Operated Valve
The Mark 80 Series is an entirely self-operated valve system that functions without the need for any external power source or supplementary expensive instrumentation. The operation of the valve is determined by temperature changes; the seats open or close as the bulb detects variations in temperature. This series exhibits high rangeability, managing flows between 10% and 90% of its rated capacity. It supports capillaries extending up to 100 feet (30 meters). Technical specifications include size options ranging from 1/4 inch to 2 inches (DN8 to DN50), various body materials such as Ductile Iron, Bronze, Carbon Steel, and Stainless Steel, and multiple end connection types including Threaded, Flanged, Socket Weld, and Butt-Weld. The valve has a flow coefficient (Cv) up to 30 (Kv up to 26) and features Jorcote seat material. The operational temperature range spans from -20°F (-29°C) to 450°F (232°C).
The Mark 80 Series is completely self-operated and requires no external power source or other expensive instrumentation to operate the valve. Depending on valve action, the seats open or close as bulb senses rise in temperature. The Mark 80 has high rangeability - controls flows from 10% to 90% of rated capacity. Available with up to 100 feet (30 meters) in capillaries.
