Description
The Belimo EP150+AKRX-E is a 2-way, fail-safe, pressure independent control valve (EPIV) combining a characterized control valve (CCV) with a proportional-integral actuator (PI) in a single, factory-assembled unit. Designed for hydronic heating and cooling applications, this EPIV delivers precise flow control regardless of differential pressure fluctuations across the system, eliminating the need for separate balancing valves and simplifying commissioning.
Key Features
- 2-way pressure independent control valve (EPIV) — combines CCV and flow controller in one assembly
- Fail-safe operation — actuator returns to closed position on power loss for system protection
- 24V AC/DC power supply for broad compatibility with building automation systems
- Proportional-integral (PI) control for accurate, stable flow regulation
- Factory-assembled and pre-calibrated — reduces installation time and commissioning complexity
- Eliminates the need for separate differential pressure controllers and balancing valves
- Maintains constant design flow regardless of system pressure variations
- Suitable for 2-pipe and 4-pipe hydronic fan coil, AHU, and terminal unit applications

Application
The EP150+AKRX-E is ideal for commercial HVAC hydronic systems where precise flow control and energy efficiency are critical. Its pressure independent design ensures that each terminal unit receives the correct flow rate at all times, improving comfort, reducing energy waste, and simplifying system balancing. The fail-safe close function protects the system during power outages, making it well-suited for chilled water and hot water coil applications in commercial buildings.
