Belimo releases the Electronic Pressure Independent Valve (ePIV) in sizes of ½” to 6”; a 2-way pressure independent characterized control valve with an integrated electronic flow meter and a powerful control algorithm. The ePIV directly measures flow by combining a
magnetic flow meter and a 2-way control valve. The actuator has a powerful algorithm that modulates the control valve to maintain the exact flow based on the control signal set by the DDC Controller. The flow reading is reported back to the controller using a standard signal, and this value can be used by the Building Automation System to perform advanced control and energy strategies.
The advantabes of 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.
- Maintains pressure independent operation down to 1 psid.
- Unlike mechanical pressure independent valves that provide an approximated/calculated fl ow 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.
