The V9000 series PICV Pressure Independent control valves are compatible with the complete range of interchangeable actuators as follows:

2 Description The V9000 series PICV pressure independent control valves consist of 3 main parts: 1. Differential Pressure Regulator The integrated diaphragm regulator keeps the differential pressure stable in the area close to the valve outlet section. The strength of the spring counteracts the differential pressure (P2-P3) on the diaphragm. When the differential pressure across the control valve varies (due to the change of the supply pressure or as a consequence of a change in the input control signal), the moving plunger (A) reacts creating a new balance and keeping the differential pressure stable. 2. Control Valve The control valve inserted between sections P2-P3 pressures, allows flow variations according to relation: Q=Kv * Δ P Where Δ P remains stable thanks to the differential pressure regulator. Within any flow rate setting it is possible to maintain a stable flow. The globe control valve plunger has an equal percentage characteristic. 3. Manual Adjustment Knob The maximum value of the flow can be preset using the graduated manual adjustment knob. The percentage value, indicated on the scale, matches the maximum flow rate percentage. This value can be changed turning the adjustment knob until it reaches the selected position (matching the percentage indicated on the scale). A locking mechanism avoids the valve set values from being changed inadvertently. Full control authority remains regardless of a manual maximum flow pre setting.

The warranty shall not include any removal and reinstallation cost involved in exchange. Benefits and Ease of Operation: Benefits: V9000 series PICV allows precise temperature control during full or partial load requirement due to constant flow output. The regulator corrects any differential pressure changes this helps to achieve a constant temperature control and reduces hunting which in return extends the life of the internal parts. V9000 series PICV control valves offer remarkable adjustment flexibility; they can be accurately set to a specific flow rate value for precise modulating control maintaining the required flow rate at any change in conditions therefore saving energy. The automatic flow rate limitation eliminates system adjustment costs. Easy on site adjustments will allow you to modify designed flow rates in the future. Since it is not necessary to adjust the valve after installation the water balancing is not necessary. Ease of Operation In order to adjust the flow rate, just set the selected maximum value using the manual adjustment knob. It is simple to choose the suitable valve as the only parameter to be considered is flow rate. V9000 series PICV valve maximum adjustment matches the maximum flow rate allowed by the pipe size on the basis of the values established by International standards. Valve authority calculation is not required Compact design allows installing the valves in small spaces such as fan coils or heating cabinets. The special manual adjustment knob allows change to the flow rate without disassembling the actuators. page 2

4 V9000 Series Valve Body Installation and Maintenance 1. User Installations Instructions: The valve has to be mounted with the arrow in the direction of the flow. Mounting it in the wrong direction can result in valve damage. If flow reversal is possible on the site a check valve should be installed. To maintain a maximum preset constant flow, a minimum differential pressure is required for the valve. 2. Maximum flow Adjustment To set the selected flow follow these steps: Lift the lock pin to unlock the selector Turn the selector to the target position Press the lock pin to lock the selector in the final position 3. Operating Control Range: In order to verify if the PICV valve is working within the 5-58psi operating range measure the differential pressure across the valve as shown in the picture. If the measured differential pressure is higher than the start up pressure, the valve is keeping the stable flow at the set value.
