New Flow Offering on 2” Electronic Pressure Independent Valve (ePIV)
Belimo expanded its 2” ePIV offering to include five new factory set flow models from 80 to 100 GPM. To achieve these new flow settings the specification for operating differential pressure range is 8-50 psid and media temperature range is 39°F to 250°F [4°C to 120°C]. For these models field set maximum flow is adjustable from 30-100 GPM, in 1 GPM increments, with the ZTH US hand held tool or PC Tool.
The ePIV is a 2-way pressure independent characterized control valve with an integrated electronic flow meter and a powerful control algorithm. The ePIV maintains flow set point regardless of differential pressure variations. It achieves this with its powerful algorithm that modulates the valve based on its measured True Flow. The ePIV:
Compensates for pressure variations and perform dynamic balancing to maintain system performance at varying loads.
Valves are selected based on coil flow rate. No Cv calculations are needed.
Valve maintains pressure independent operation down to 1 psid.
Unlike mechanical pressure independent valves that provide an approximated/calculated flow feedback, the built-in electronic flow meter provides True Flow as a feedback to BAS systems.
Built-in CCV technology with high close-off pressure and zero leakage eliminates “ghost energy” losses in the system.
ZTH US handheld tool provides fast and easy access to settings and values.
