Belimo EP075+LRX-E Pressure Independent Valve 3/4 in 11 Gpm

Product Description

The BELIMO EP075+LRX-E is a pressure independent control valve (PICV) assembly designed for hydronic HVAC systems requiring precise flow control regardless of system pressure fluctuations. This 2-way valve combines an equal percentage flow characteristic with an integrated electric actuator, delivering a maximum flow of 11 GPM through a 3/4 inch female NPT threaded connection. The stainless steel trim construction handles a close-off pressure of 200 psi. The LRX-E actuator operates on 24 volts AC or DC and supports BACnet MS/TP, Modbus RTU, and MP-Bus communication protocols, making it well suited for building automation system integration. Licensed HVAC technicians and mechanical contractors install this assembly in commercial and light commercial hydronic applications.

This valve assembly is used in variable flow hydronic systems where maintaining a constant design flow rate at individual terminal units is critical. Typical applications include fan coil units, air handling units, and chilled or hot water distribution systems in commercial buildings. The communicating actuator allows direct integration into BAS platforms for flow setpoint adjustment and monitoring. The non-spring return design means the actuator holds its last position on power loss rather than failing to a fixed position, a consideration that must be evaluated during sequence of operations planning.

Key Features

• Pressure independent operation maintains design flow rate across varying system differential pressures
• Equal percentage flow characteristic for precise modulating control throughout the valve stroke
• Supports BACnet MS/TP, Modbus RTU, and MP-Bus communication for BAS integration
• Accepts both analog and communicating control signals for flexible installation options
• Stainless steel trim rated to 200 psi close-off pressure for reliable shutoff
• Non-spring return actuator with 45 in-lb torque output
• 24 volts AC or DC supply voltage compatibility

Compatibility

Designed as an OEM-style pressure independent control valve assembly for 2-way hydronic piping configurations using 3/4 inch female NPT threaded connections in commercial HVAC systems.

Installation Notes

Installation should be performed by a licensed mechanical contractor or qualified HVAC technician familiar with hydronic piping systems and low-voltage building automation wiring. Isolate and depressurize the hydronic system before removing or installing the valve assembly, and verify system pressure does not exceed the rated close-off pressure. Low-voltage control wiring must comply with NEC requirements and the BAS manufacturer wiring specifications for the selected communication protocol. Confirm actuator fail position behavior is acceptable for the sequence of operations before commissioning.
