Johnson Controls VG7241LT+7152G Valve Assembly

The Johnson Controls VG7241LT+7152G is a high-performance 3/4 inch globe valve assembly designed for precise proportional control of hot water, chilled water, and saturated steam in commercial HVACR systems. Built with a robust cast bronze body and brass trim, this 2-way normally open valve features an equal percentage flow characteristic, ensuring stable modulation and linear heat transfer across varying load conditions. The assembly is factory-coupled with the VA-7152-1001 non-spring return electric actuator, which operates on 24VAC power and accepts a 0-10VDC control signal for seamless integration with modern Building Automation Systems (BAS).

Engineered for technical reliability, the VG7241LT+7152G utilizes NPT threaded connections and a 7.3 Cv flow coefficient, making it ideal for fan coil units, unit ventilators, and reheating coils. The VA-7152 actuator provides a minimum of 90 lb force to ensure tight shutoff against high differential pressures, while the magnetic clutch mechanism protects the synchronous motor from stall conditions. With a standard threaded stem and long-life ring pack packing, this assembly reduces maintenance overhead and provides exceptional service life in demanding hydronic applications.

• Optimized Control: The equal percentage flow design provides superior part-load performance and prevents hunting in modulating loops.
• Direct-Mount Efficiency: The VA-7152-1001 actuator mounts directly to the VG7000 series valve body without complex linkages, simplifying field service.
• High Capability: Features a cast bronze body rated for saturated steam up to 35 psig and water temperatures from 35°F to 284°F.
• Flexible Signal Handling: The 0-10VDC proportional input allows for precise positioning and real-time response to controller demands.
• Durable Construction: Brass trim and ANSI Class IV leakage rating ensure energy efficiency and reliable positive closeoff.

• What is the default position of the valve upon power loss? This is a non-spring return (NSR) assembly; the valve will remain in its last position if 24VAC power is interrupted.
• Is this assembly compatible with steam applications? Yes, the VG7241LT with brass trim is rated for saturated steam up to 35 psig.
• Can the actuator action be reversed? Yes, the VA-7152 actuator features jumpers to select between direct and reverse action depending on your controller logic.
