Belimo Electronic Pressure Independent Valve (ePIV)

Belimo Electronic Pressure Independent Valves (ePIV) integrate a high-accuracy electronic flow meter with a 2-way pressure independent control valve and intelligent actuator. The built-in control algorithm continuously regulates valve position based on actual measured flow, ensuring that the required flow rate is maintained regardless of system pressure variations.

Unlike conventional balancing solutions, ePIV valves provide continuous dynamic balancing without requiring separate balancing valves. Real-time flow feedback can be transmitted directly to DDC or BMS controllers for advanced HVAC optimization, energy management, system monitoring, and predictive maintenance.

Belimo ePIV valves are ideal for controlling chilled water coils, hot water coils, air handling units (AHUs), fan coil units (FCUs), VAV reheat coils, and other hydronic HVAC applications requiring accurate flow control and long-term energy efficiency.

Main Features

Belimo ePIV provides precise pressure independent flow control while continuously measuring actual water flow and automatically compensating for pressure fluctuations throughout the system. By eliminating coil overflow and maintaining accurate design flow, the valve reduces pumping energy consumption, improves heat transfer efficiency, minimizes Low Delta T syndrome, and simplifies system commissioning. Adjustable maximum flow settings and selectable linear or equal percentage control characteristics provide excellent flexibility for a wide range of HVAC applications.
