The Electronic Pressure Independent Valve (ePIV) offers a constant flow regardless of pressure variations in the system. The ePIV is a two-way flange valve which is unaffected by pressure variations in a system. The ePIV directly measures flow by combining a magnetic flow meter and a 2-way control valve.
The following table illustrates the factory selectable flows. Changing the flow to a custom value can only be done in the field using the ZTH-GEN hand tool or the PC-Tool. Factory set flows are 5% from nominal flow apart. The ePIV valve has an accuracy of ±10% of nominal flow. This allows the user to be able to cover all flows. If the factory set flow does not match the coil size then select the next GPM value from the table. All actuators are configurable, including different options for cables and signal configurations.
*Maximum flow for each body size.
The ePIV now ranges in size from 2½" to 6" and complements the existing line of Pressure Independent Characterized Control Valve (PICCV).
