Belimo B219+LRX24-MFT Characterized Control Valve with Programmable Actuator - 3/4

The Belimo B219+LRX24-MFT is a complete characterized control valve assembly featuring a 3/4" NPT two-way valve paired with a configurable non-spring return actuator. This precision-engineered assembly combines the high close-off capabilities of a ball valve with a specialized characterizing disc that ensures an equal percentage flow characteristic for superior HVAC control performance.

Valve Specifications (B219):

• 2-way characterized control valve with 3/4" NPT threaded connections
• Flow coefficient (Cv) of 10 for optimal flow capacity
• Stainless steel ball and stem construction for long-lasting durability
• Body pressure rating of 600 PSI with 200 PSI close-off pressure
• Equal percentage flow characteristic for precise modulating control
• Suitable for chilled or hot water applications, including up to 60% glycol solutions

Actuator Specifications (LRX24-MFT):

• Multi-Function Technology (MFT) programmable actuator with advanced configuration options
• Non-spring return (NSR) operation for fail-in-place functionality
• 24 VAC/DC power supply with low 2.5W power consumption during operation
• Proportional control with 2-10 VDC modulating control signal (also supports 4-20 mA with resistor)
• 45 in-lb torque rating for reliable valve actuation
• Plenum-rated cable with selectable length options (1m, 3m, or 5m)
• UL 2043 compliant for air plenum installation per NEC and IMC requirements
• Maintenance-free operation with electronic overload protection

Common Applications:

• Air handling unit heating and cooling coil control
• Fan coil unit temperature regulation
• Unit ventilator applications
• VAV box re-heat coil control
• Bypass loop control in variable flow hydronic systems

The characterized control valve design prevents control loop hunting, extending component lifespan and optimizing energy consumption. The programmable MFT actuator allows for custom configuration to meet specific application requirements, making this assembly ideal for demanding commercial HVAC applications requiring precise, reliable control.
