Johnson Controls VG7251LT+7150G 2-Way 3/4" Bronze Globe Valve with VA-7150 Non-Spring-Return Electric Actuator

The Johnson Controls VG7251LT+7150G is a factory-assembled, two-way actuated globe valve assembly combining the VG7251LT cast bronze valve body with the VA-7150-1001 non-spring-return electric actuator. Designed for precise flow regulation in commercial HVAC hydronic systems, this assembly controls hot water, chilled water, glycol solutions, and steam in response to a building automation controller.

The VG7251LT valve body is a Series VG7000 cast bronze globe valve with the following characteristics:

• Configuration: Two-way, normally open (N/O), push-down-to-close (PDTC)
• Valve Size: 3/4 inch
• Flow Coefficient: Cv 7.3
• End Connection: Union globe (UnGl) — union NPT threaded connections for easy installation and removal
• Trim Material: Brass
• Stem Type: Standard threaded stem
• Flow Characteristic: Equal percentage
• Rangeability: 100:1
• Leakage Rate: 0.01%
• Safe Working Water Pressure: 308 psi
• Safe Working Steam Pressure: 38 psi
• Operating Temperature Range: 35°F to 248°F
• Packing Material: Ethylene propylene
• Media Compatibility: Water, steam, and water-glycol solutions up to 50%

The VA-7150-1001 actuator is a VA-715x Series non-spring-return (NSR) electric actuator with the following characteristics:

• Control Type: On/Off and floating point
• Supply Voltage: 24 VAC, 50/60 Hz
• Close-Off Pressure: 90 psi (incremental/floating)
• Return Type: Non-spring-return (NSR) — valve holds last position on power loss
• Mounting: Direct-coupled, no linkage required
• Magnetic Clutch: Protects internal gearing from overload

The VG7000 Series platform offers complete actuator interchangeability, making field retrofit and actuator swaps straightforward using standardized mounting kits. This assembly is ideal for air handling units, fan coil units, chiller and boiler loops, and other commercial hydronic control applications.
