Johnson Controls VG7251NT+7150G 1-Inch 2-Way Unglued Globe Valve with VA7150 Electric Actuator, 11.6 Cv, 24V

The Johnson Controls VG7251NT+7150G is a factory-assembled combination of a 1-inch, 2-way unglued bronze globe valve paired with a VA7150-series electric actuator. Designed for HVAC hydronic systems, this valve and actuator assembly provides reliable on/off or floating-point control of hot water, chilled water, and steam applications in commercial building automation systems.

Key Features:

• Valve Size: 1-inch NPT end connections (unglued/threaded)
• Flow Coefficient (Cv): 11.6 — engineered for accurate flow control
• Actuator Voltage: 24V AC/DC input
• Control Type: 3-wire floating-point (open/close/common) control signal
• Valve Body: Bronze construction, 2-way configuration
• Actuator: VA7150G spring-return electric actuator for fail-safe operation
• Stem Design: Linear stem motion for precise throttling
• Application: Hydronic heating, cooling coil control, and building automation systems

The VG7251NT valve body features a threaded (NPT) unglued connection, making field installation and replacement straightforward without soldering. The integrated VA7150G actuator provides spring-return fail-safe functionality, ensuring the valve returns to a known position upon loss of power — a critical safety feature for HVAC system protection.

This pre-assembled combination simplifies procurement and installation, and is compatible with Johnson Controls and third-party building automation controllers that output standard 24V floating-point signals. Ideal for commercial HVAC contractors, mechanical engineers, and building automation professionals.
