â—† Reset function
â—† Stages (**8) and stage duration (*****9 Sec) settings
â—† System working stage indication (Service or regeneration stage indication)
â—† Data protection after power cut: settings and data can be stored for 3 years.
â—† Waterproof and rotproof enclosure

JMA stager controllerMultiple valve controller working principle:
The stager may be manually operated or driven by an electric motor that operated through an adjustable timer or flowmeter program. The stager functions by opening and closing its ports, singly or in combination, in a sequence that fit the need of the system. The positions in the sequence correspond to the number of stager in the process (See chart 1). The port that are opened allow the pressurized fluid to flow to and operate some diaphragm valves, while venting other valves—allowing them to return to their normal positions.
The stagers can use either hydraulic or pneumatic control fluid. Continuous electrical power is not required to maintain the positions of the valves such as in a solenoid operated system. Greatly avoid the system breakdown because of power failure.
All types of complex application can be controlled by stager controller system through correct design and combination of the stagers.
