Johnson Controls VG7241RT+7152G Valve Assembly

Designed for professional contractors, the Johnson Controls VG7241RT+7152G is a high-performance 1 1/2" NPT globe valve assembly engineered for precise flow regulation in HVAC systems. This heavy-duty 2-way control valve features a robust cast bronze body and durable brass trim, ensuring reliable performance when managing hot water, chilled water, and saturated steam up to 38 psig. Utilizing an equal percentage flow characteristic, this assembly delivers a 28.9 Cv rating, providing superior throttling across its entire stroke. It is factory-paired with a VA-7152 non-spring return electric actuator, which operates on 24Vac and accepts a 0-10Vdc proportional signal for seamless integration with modern building automation systems (BAS). The direct-mount design eliminates the need for complex linkages, and the magnetic clutch mechanism protects the actuator motor during stall conditions, significantly extending the service life of the threaded connection valve in high-demand commercial environments.

• Superior Control: The equal percentage flow design ensures stable temperature control and linear heat output in complex piping loops.
• High Close-Off Capability: Rated for a 34 psi close-off pressure, ensuring leak-free performance and maintaining ANSI Class IV shut-off standards.
• Rugged Construction: The cast bronze body and ring pack packing provide industry-leading durability for hydronic heating and cooling applications.
• Simplified Maintenance: Features a standard bonnet and threaded stem, allowing for easy field retrofit or repacking without removing the valve from the line.
• Professional Grade Actuation: The proportional 0-10Vdc actuator offers quiet operation (35 dBA) and a magnetic clutch for overload protection.

What is the maximum fluid temperature for this assembly?
The Johnson Controls VG7241RT+7152G is rated for fluid temperatures ranging from 35°F to 284°F (2°C to 140°C), making it suitable for both chilled water and low-pressure steam applications.

Can the actuator be replaced without disturbing the piping?
Yes, the VA-7152 actuator features a direct-mount yoke and a single set screw, allowing for fast removal or replacement without disconnecting the valve body from the NPT lines.

Is this valve assembly suitable for potable water?
No, this unit is constructed from copper alloys containing lead and is specifically designed for closed-loop HVAC control valve applications, not for domestic or drinking water systems.
