1 asic Valve??????? I-9-D Automatic Metering Valve (AMV) The EMAD Model I-9-D is a unique product integrating both a vertical turbine oltman-type water meter and a pilot operated, diaphragm actuated control valve, with a built-in auxiliary shut-off pilot for batch applications. hen this unique assembly delivers a preset quantity of water, its control head mechanism mechanically shifts the shut-off pilot. This automatically and smoothly closes the control valve, stopping the flow of water. The I-9-D provides the full spectrum of metering functions - from simple visual readout, through non-computerized dose control, to pulse output for computerized data capture and control - while simultaneously allowing for numerous control valve features such as pressure, level and flow control. anging in size from 1 1 /"; DN4 through 1"; DN5, the is specifically designed for metering and control applications in agricultural and landscape irrigation as well as municipal and industrial water supply systems. The flow metering unit is vertical to the pipeline and includes an impeller with integrated inlet and outlet flow straighteners. This internal design eliminates the need for straightening distances, enables vertical or horizontal installation, and ensures accuracy even when the valve is partially open during pressure or flow control tasks. The impeller assembly shaft serves as the closure assembly guide, and for centralizing and tightening all internal parts both in their position and to one another. The basic Model I-9-D combines simple and reliable construction with superior performance, while at the same time being virtually free of the typical limitations associated with other single chambered valves. The relatively high impeller housing raises the location of the vulcanized seal seat above the valve body. This results in remarkable cavitation resistance and a smooth mushroom-shaped flow where the valve body is at maximum distance from the flow. The closure assembly, combining a rugged radial disk harnessed to a flexible fiber reinforced diaphragm, slides on the guide along the full valve travel. The diaphragm is carefully balanced and peripherally supported to avoid distortion, resulting in long-life and controlled actuation even under harsh conditions. One diaphragm and spring fully meets the valve's operating pressure range requirements. The cover is removable via fastening bolts for quick in-line inspection and service. All the internal assemblies can be easily removed from the valve body with no need for disassembling the valve from the line.

2 EMAD Irrigation Principle of Operation On-Off Modes, Automatic Metering Valves m m AMV Closed AMV Open The shut-off pilot hydraulically connects the AMV inlet pressure to the control chamber. Setting the AMV closes the shut-off pilot, thereby discharging pressure from the control chamber and opening the AMV. Upon delivering the preset water quantity, the shut-off pilot switches open to divert line pressure into the AMV control chamber. This causes the AMV to shut, stopping the flow of water. On-Off Modes, Sequential Automatic Metering Valves m m m Previous AMV, Closed Current AMV, Open Next AMV, Set & Closed Each AMV is manually preset to deliver a desired quantity of water. As long as the Previous AMV is set & open, it transmits pressure that enters the Current AMV control chamber through its sequential shut-off pilot, closing it. hen the Previous AMV shuts itself off, it drains the Current AMV control chamber through both AMV's sequential shut-off pilots, opening the Current AMV. The Current AMV inlet pressure is transmitted to the Next AMV, holding it closed until the Current AMV shuts itself off.

3 Principle of Operation -ay Modulating Modes, Pressure educing Pilot Modulating to Close The restrictor continuously allows line pressure into the control chamber, while the pilot controls outflow from the control chamber. Throttling when it senses a pressure rise, the pilot causes pressure to accumulate in the control chamber, forcing the valve to modulate closed. Modulating to Open The pilot modulates open when it senses a pressure drop, releasing greater flow from the control chamber than the restrictor can allow in. This causes the accumulated pressure in the control chamber to drop, and the valve to modulate open. Zero Flow Position Upon delivering the preset quantity of water, the AMV shut-off pilot automatically switches, closing the hydraulic relay valve. This causes pressure to accumulate in the AMV control chamber, shutting the AMV. 3-ay Control Modes, Pressure educing AMV Set, Fully Open Position hen upstream pressure drops, the pilot blocks the pressure port and opens the drain port, venting the control chamber to the atmosphere. This fully opens the valve, minimizing head loss. AMV Set, Modulating to Close Upon pressure rise the pilot switches, blocking the drain port and opening the pressure port. This pressurizes the control chamber, forcing the valve to modulate closed. Automatic Shut-Off Upon delivering the preset quantity of water, the AMV shut-off pilot automatically switches, blocking the pilot while directing line pressure into the control chamber, thereby causing the AMV to shut.

4 Principle of Operation /3-ay Modulating Modes, Flow Control AMV Set, Modulating to Close Should demand rise above setting, the increasing flow dynamic-force moves the paddle, which thereby pushes up the pilot trim, causing a negative ratio between water flow into and out of the control chamber. Pressure then accumulates in the control chamber, forcing the AMV to throttle closed. AMV Set, Modulating to Open hen demand is below setting, the pilot's spring force pushes the pilot trim down, thereby causing a negative ratio between water flow into and out of the control chamber. Pressure is then released from the control chamber, enabling the AMV to modulate open 1345 Automatic Shut-Off Upon delivering the preset quantity of water, the AMV shut-off pilot automatically switches, directing line pressure through the shuttle valve into the control chamber, thereby causing the AMV to shut.
