Johnson Controls VG7243LT+3003D Valve Assembly

Maximize your hydronic system efficiency with the Johnson Controls VG7243LT+3003D. This professional-grade VG7000 Series valve assembly features a 3/4" NPT connection and a robust cast bronze body built for long-term reliability in demanding HVAC applications. Engineered with stainless steel trim, this 2-way globe valve is ideal for regulating hot water, chilled water, or 100 psig saturated steam. The normally open (N.O.) configuration ensures fail-safe operation, while the equal percentage flow characteristic provides precise modulating control for superior climate stability.

The integrated V-3000-8003 enclosed pneumatic actuator delivers consistent performance with a 4-8 PSI spring range and spring-return action. Designed for seamless integration into existing pneumatic control loops, this assembly offers a high 7.3 Cv flow coefficient and handles close-off pressures up to 108 psig. Contractors depend on the VG7243LT+3003D for its field-replaceable components and compatibility with standard Johnson Controls mounting hardware, ensuring minimal downtime during routine maintenance or system upgrades.

• Industrial Durability: Cast bronze body and stainless steel internal trim resist corrosion and handle high-temperature steam applications up to 338°F.
• Precise Flow Control: The equal percentage flow design allows for accurate linear heat transfer to meet specific zone demands.
• Reliable Actuation: The 3003D enclosed actuator protects the diaphragm from environmental debris and unauthorized adjustments.
• Versatile Media Compatibility: Rated for water, 50/50 glycol solutions, and saturated steam systems.

• How does the normally open function work during a signal loss? Upon loss of pneumatic pressure, the internal spring return pushes the stem up to keep the valve in the fully open position.
• Can this valve be used for steam applications? Yes, the stainless steel trim allows it to handle saturated steam up to 100 psig.
• What air connection does the actuator require? It is designed for standard 1/8" NPT air connections typically found in pneumatic control systems.
