Mark 80 Series Temperature Regulator
Self-Operated Control for Steam, Water, and Process Applications

The Jordan Valves Mark 80 Series is a self-operated temperature regulator engineered for accurate and efficient control in industrial systems. No external power or instrumentation is required—this temperature regulator uses a sensor bulb and capillary tube to automatically respond to rising temperatures, opening or closing the valve accordingly.

Key Features:

• Self-Operated: No external power source or expensive instrumentation required
• Versatile Applications: Ideal for steam, water, air/gas, and chemical processes
• Sizes & Capacity: Available in sizes up to 2” (DN50) with Cv up to 70 (Kv to 60.5)
• Connection Options: Choose from threaded or flanged ends

Mark 80 Series Advantages:

• No External Power Needed: Maintains system simplicity and reliability
• Responsive Control: Seats open or close as the bulb senses a temperature rise
• High Rangeability: Controls flows from 10% to 90% of rated capacity
• Extended Capillaries: Available up to 100 feet (30 metres) for flexible installation

This regulator integrates well with globe valves, steam traps, and other valve control equipment for comprehensive thermal management.
