The Humphrey ProControl Series are proportional valves. Adjusting input voltage, or current to a proportional valve results in a corresponding output media flow. The miniature ProControl PC30 has precise control up to 300 liters per minute. Three orifice sizes are available: 0.156”, 0.188” and 0.250”.
The 0.156” orifice PC30 can be specified with a maximum pressure rating of either 25, 50 or 100 psi.
Here is the performance chart of the orifice size at the pressure ratings available.
NOTE: the right side portion of each curve corresponds to current and flow increasing and the left side of each curve corresponds to current and flow decreasing.
