Johnson Controls VG7241ST+7152G Valve Assembly

The Johnson Controls VG7241ST+7152G is a high-performance 2-way globe valve assembly designed for precise flow regulation in demanding HVACR applications. Operating on a 24VAC power supply, this 2" NPT assembly features a robust cast bronze body and brass trim, ensuring reliable service with hot water, chilled water, and 50/50 glycol solutions. The integrated VA-7152 series electric actuator provides 0-10 VDC proportional control, allowing for an equal percentage flow characteristic that translates to stable and linear temperature management in large-scale air handling and terminal unit systems.

This non-spring return actuator delivers a minimum of 90 lb-f of torque, maintaining position upon power loss to prevent sudden system shifts. Engineering specifications include an ANSI Class 250 static pressure rating and a Cv of 46.2, making it a staple for contractors requiring durable Johnson Controls VG7241ST components. The design incorporates standard ring pack packings for extended service life and a magnetic clutch to ensure tight close-off without risking motor damage during stall conditions. For field efficiency, the assembly utilizes a unique yoke for direct mounting, simplifying the replacement of legacy proportional valve actuators.

• Refined Control Accuracy: The equal percentage flow characteristic provides predictable performance across the entire stroke of the 2" globe valve.
• Rugged Hardware: Cast bronze construction and brass seats are engineered to withstand the thermal stresses of steam and hydronic HVAC cooling and heating.
• Maintenance-Friendly Design: The standardized bonnet and stem allow for rapid field mounting and actuator interchangeability without removing the valve body from the line.
• Consistent Shut-Off: Integrated magnetic clutch maintains constant force at the seat, compensating for wear to prevent internal leakage.

• What control signals are compatible with this unit? It accepts a standard 0-10 VDC signal, with internal jumpers available for 0-5 or 5-10 VDC configurations.
• Can this be used for steam applications? Yes, the VG7000 series bronze control valves are rated for saturated steam up to 35 psig.
• Does the valve return to a specific position if power is lost? No, as a non-spring return model, the valve will maintain its last position relative to the last received signal.
