Belimo B217+LRX24-MFT 3/4" NPT Characterized Control Valve with Programmable Actuator

The Belimo B217+LRX24-MFT is a 2-way characterized control valve (CCV) featuring a 3/4" NPT threaded connection with a Cv rating of 4.7, factory-assembled with an LRX24-MFT configurable non-spring return actuator. This precision-engineered assembly delivers reliable proportional control for HVAC hydronic applications including air handling units, fan coil units, unit ventilators, and VAV box reheat coils.

Valve Construction and Features:

• 3/4" NPT internal thread connections for easy installation
• Stainless steel ball and stem for superior corrosion resistance and durability
• Nickel-plated forged brass body rated for 600 psi working pressure
• Cv 4.7 flow coefficient (9.4 GPM @ 4 psi differential pressure)
• Equal percentage flow characteristic with characterizing disc for stable, precise control
• Compatible with chilled or hot water up to 212°F and glycol solutions up to 60%

LRX24-MFT Actuator Specifications:

• Non fail-safe (non-spring return) operation with electronic overload protection
• AC/DC 24V nominal voltage (AC 19.2-28.8V / DC 21.6-28.8V range)
• 2-10 VDC proportional control signal (MFT programmable)
• 2.5W power consumption during operation, 1.2W at rest
• 90° rotation with maintenance-free operation
• NEMA 2 / IP54 protection rating
• 18 AWG plenum-rated cable with 1/2" NPT conduit connector
• UL 2043 compliant for air plenum use per NEC Section 300.22(C)
• Operating temperature range: -22°F to 122°F (-30°C to 50°C)

The MFT (Multi-Function Technology) programmable actuator allows field customization of control parameters using Belimo's service tools, providing flexibility for diverse system requirements. The equal percentage flow characteristic prevents control loop hunting, optimizing energy consumption while extending component life. This pre-assembled valve and actuator combination eliminates the need for multiple pipe reductions while delivering comparable Cv values to larger globe valves.
