Product Information


The AquaMatic stager is a motor-driven rotary multi-port pilot valve, which is used to control a set of individual diaphragm valves in a predefined sequence. Stagers are constructed of durable, non-corroding, self-lubricating material for long and trouble-free operation. Stagers are operated by an electric motor controlled by an adjustable timer. In the event of a power failure, AquaMatic brand stagers can be manually advanced through the different positions.

The stager pressurizes and vents various ports in a predefined sequence allowing valves to open and close the system. The pressure of the control line into the stager, either hydraulic or pneumatic must be equal to or greater than the line pressure in the system. The control pressure source must be constant and relatively clean, using a filter in the control line as a precautionary source.
