Information About EP100+LRX-E
The EP100+LRX-E is part of Belimo’s electronic pressure independent valve platform developed to maintain stable hydronic flow regardless of system pressure variations. It integrates a precision flow control valve with a communicating actuator that supports BACnet MS/TP, Modbus RTU, and MP-Bus for seamless building automation integration. The valve features adjustable maximum flow, equal percentage control behavior, and precise modulation to support energy-efficient system operation. Configuration and commissioning are simplified through NFC using the Belimo Assistant 2 application.
Key Features
- Pressure Independent Flow Control Technology: Maintains constant and accurate flow rates despite fluctuating differential pressure conditions within the system.
- Integrated Communicating Actuator: Native BACnet MS/TP, Modbus RTU, and MP-Bus enable direct digital integration with building management systems.
- Precise Modulating Performance: Supports 2…10 V, variable VDC, and optional 4…20 mA control for accurate valve positioning.
- Adjustable Maximum Flow Setting: V’max can be set between 25% and 100% of nominal flow to match system design requirements.
- High Control Accuracy: Achieves ±5% flow accuracy with repeatable control performance across the operating range.
- Quiet And Efficient Operation: Low operating noise and minimal power consumption support use in occupied HVAC environments.
- Simplified Commissioning Via NFC: Configuration and diagnostics can be performed wirelessly using the Belimo Assistant 2 app.
The EP100+LRX-E delivers the reliability and precision required for accurate, digitally integrated pressure independent flow control in modern HVAC hydronic systems.
