BODY BASIC VALVE DIMENSIONS ELECTRICAL REQUIREMENTS Nominal Supply Voltage (VDC) Nominal Coil Resistance (Ohms) @ 20°C Control Current at Maximum Flow (mA) BASIC CONTROL: proportional valve can be controlled by either voltage or current; however, it is highly recommended that current control be employed to ensure the most repeatable valve ﬂow performance. SUGGESTED PWM CONTROL: For PWM control, the signal applied to the valve should have a frequency of 5 kHz or greater. Optimal frequency will be application dependent.
