Johnson Controls VG7243NT+3008D Valve Assembly

The Johnson Controls VG7243NT+3008D is a rugged, field-ready 2-way normally open globe valve designed for precision modulation in demanding HVACR environments. This 1-inch NPT assembly features a high-capacity 11.6 Cv equal percentage flow characteristic, making it ideal for the accurate control of hot water, chilled water, or 38 psig saturated steam. Built with a heavy-duty cast bronze body and stainless steel trim, this unit is engineered for longevity in systems with up to 50% glycol solutions.

The integrated V-3000-8012 pneumatic actuator provides reliable spring return functionality with a 4-8 PSI spring range, ensuring a fail-safe open position during signal loss. Designed for direct mounting without complex linkages, the VG7000 Series offers a compact footprint for tight mechanical rooms. With an ANSI Class 250 static pressure rating and a fluid temperature envelope of 35°F to 338°F, this valve assembly provides the robust shutoff and 0.05% maximum flow leakage performance that professional contractors require for high-performance hydronic loops.

• Precision Modulation: Equal percentage flow ensures stable control across the entire stroke, preventing system hunting.
• Industrial Durability: Stainless steel plug and stem provide superior resistance to corrosion and wear compared to standard brass trim.
• Serviceable Design: The VG7243NT+3008D supports in-line repacking, significantly reducing downtime during routine maintenance.
• High Steam Compatibility: Capable of handling saturated steam up to 100 psig at the valve body (actuator dependent).
• Fail-Safe Security: The normally open configuration ensures constant flow in heating or cooling coils if control air pressure is lost.

What is the maximum close-off pressure for this assembly?
The VG7243NT+3008D typically provides a close-off pressure of approximately 32 psi when utilizing the 4-8 psi spring range pneumatic actuator.

Can this valve be used for steam applications?
Yes, the stainless steel trim and PTFE V-ring packing allow for saturated steam service, generally rated up to 38 psig in this configuration.

Is the actuator field-replaceable?
The V-3000 pneumatic actuator is designed for easy removal and replacement on VG7000 series valves using standard 1-inch and 1-1/4 inch mounting kits.
