Small Proportional Solenoid Valve
MODEL 2900 SERIES |
| |
 |
This small,or rather miniature,proportional solenoid valve maintains flow control characteristics of hysteresis within 15%(full-scale current)and is perfect for automatic gas flow control of gas chromatographs and various other analyzers. Because of its superior resolution,Model 2900 is also ideal for control of precision control of pressure. |

| Features |
- High-performance proportional valve for a single power source ultra-compact in size,light in weight
- Low power consumption(2W)
- Annealed magnetic materials,together with a specially designed flat spring,perfectly eliminate flow fluctuations caused by vibrations due to plunger run-outs and frictions.
- The incorporated magnetic yoke is annealed after precutting(and not bending)to remove magnetic flux passage interference,thereby to enhance magnetic power.
- Minimum hysteresis available in the industry(within 15%)
- Patent applied for (United States Patent and Trademark Office)

*1:Custom-ordered model.Contact us for information on details.
*2:PWC=Pulse Width Coding
*3:Temperature coefficient of the Model 2900 coil copper wire resistance is Rt=RoCK(1{0.004xt°C). If you need to use voltage values for control, use the product in the environment where ambient temperature does not vary in large measure. Where there are large variations in ambient temperature, it is recommended to use current control. |
