JMA Controller

JMA Controller

The stager may be manually operated or driven by an electric motor that operated through an adjustable timer or flow-meter 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.
