Belimo EP200+AKRX-E Pressure Independent Valve 2in 66GPM

Product Description

The BELIMO EP200+AKRX-E is a pressure independent control valve (PICV) assembly combining a 2-way, 2 inch body with an electric spring-return actuator for use in hydronic HVAC systems. The valve delivers equal percentage flow characteristics at a rated capacity of 66 GPM and a 200 psi close-off pressure, making it suitable for demanding commercial hydronic applications. The actuator operates on 24 volts AC or DC and provides 180 in-lb of torque with spring-return fail-safe action. Communication is supported via BACnet MS/TP, Modbus RTU, and MP-Bus protocols, enabling full integration into building automation systems. Installation and commissioning are performed by licensed HVAC or controls technicians.

This valve assembly is designed for commercial and light industrial hydronic heating and cooling systems where pressure independent flow control is required. The 2 inch female NPT threaded connection simplifies installation into existing piping infrastructure. The modulating BACnet MS/TP, Modbus RTU, and MP-Bus control capability supports integration with modern DDC and BAS platforms, making this assembly appropriate for variable flow air handling, chilled water, and hot water coil applications in commercial buildings.

Key Features

• Pressure independent design maintains consistent flow across varying system differential pressures
• Equal percentage flow characteristic provides precise capacity control across the operating range
• 66 GPM rated flow capacity with 200 psi close-off pressure
• Spring-return actuator provides fail-safe positioning on loss of power
• Multi-protocol communication: BACnet MS/TP, Modbus RTU, and MP-Bus
• Stainless steel trim for corrosion resistance in hydronic service
• 2 inch female NPT threaded connection for straightforward field piping

Compatibility

Designed as an OEM-style PICV assembly for commercial hydronic HVAC systems requiring pressure independent flow control with BACnet MS/TP, Modbus RTU, or MP-Bus network integration at 24 volts AC or DC.

Installation Notes

Installation should be performed by a licensed HVAC or building controls technician familiar with hydronic piping and low-voltage control wiring. Isolate and depressurize the hydronic system before installation and verify that system pressure does not exceed the 200 psi close-off rating. Follow applicable mechanical and electrical codes, including local adoptions of the IMC and NEC, for piping and low-voltage wiring. Power down the control circuit before making or breaking any actuator wiring connections.
