Jordan MK57 series is a pilot operated Pressure Sustaining or Back Pressure valve and provides greater accuracy and lower offset than can be achieved with self acting valves. It is available in sizes 1/2″-6″ (Cv’s 5.0-395) and consists of a main valve with a small, pilot valve. The Mk57 combines the short stroke of the sliding gate with the action of a pilot valve to create a faster, more accurate response (less droop as flows increase). Can be used where greater accuracy is required than self acting valves or where control systems are not an option.
