Johnson Controls VG7243GT+7152G Valve Assembly

Increase system precision with the Johnson Controls VG7243GT+7152G, a factory-coupled globe valve assembly designed for high-demand HVAC applications. This 1/2" NPT valve features a cast bronze body and stainless steel trim, specifically engineered to regulate the flow of hot water, chilled water, or 100 psig saturated steam. The VG7243GT body is paired with the VA-7152-1001 non-spring return proportional actuator, providing a constant 90 lb force output for positive close-off and reliable control. Use this assembly to maintain equal percentage flow characteristics in proportional control circuits, driven by a 0-10Vdc signal. The magnetic clutch protects the motor and gearing during stall conditions, while the 24Vac synchronous motor ensures quiet, efficient operation. Built to meet ANSI Class 250 pressure and temperature standards, this assembly is a rugged choice for building automation systems (BAS) and commercial hydronic piping.

• Stainless Steel Trim: Provides superior resistance to corrosion and wear compared to brass, making it suitable for 100 psig saturated steam.
• Magnetic Clutch: Ensures reliable positive close-off while extending the life of the motor by preventing gear damage in stall conditions.
• Proportional Precision: The VA-7152 actuator delivers accurate 0-10Vdc proportional control for modulating applications.
• Compact Footprint: The low-profile yoke design allows for easy installation in tight mechanical rooms or terminal unit cabinets.
• Field Versatility: Features selectable direct or reverse action for seamless integration with various HVAC controllers.

What is the maximum fluid temperature for this assembly?
The VG7000 stainless steel trim series is rated for fluid temperatures ranging from 35°F to 338°F, covering both chilled water and saturated steam up to 100 psig.

Can I manually operate the valve if power is lost?
Since this is a non-spring return proportional actuator, it will maintain its last position upon loss of 24Vac power. Manual positioning is possible through the internal drive mechanism during commissioning.

What is the close-off pressure for the 4.6 Cv model?
The VG7243GT paired with a 90 lb force actuator typically provides a close-off pressure rating of approximately 135 psi, ensuring tight shutoff in most standard hydronic loops.
