Johnson Controls VG7243GT+3008E Valve Assembly

The Johnson Controls VG7243GT+3008E is a high-performance 2-way normally open globe valve assembly designed for precise flow modulation in commercial HVAC systems. This 1/2-inch NPT cast bronze valve body features stainless steel trim, ensuring superior resistance to corrosion and wear when handling hot water, chilled water, or 100 psig saturated steam. With an equal percentage flow characteristic and a 4.6 Cv rating, this assembly provides the linear control necessary for maintaining accurate temperature setpoints in demanding hydronic loops.

The unit is powered by a V-3000 series exposed pneumatic actuator with a 9-13 PSI spring range. This spring-return configuration ensures a fail-safe open position, critical for preventing system freeze-ups or maintaining flow during power or signal loss. Built to ANSI Class 250 standards, the VG7243GT+3008E can withstand static pressures up to 400 psi and fluid temperatures ranging from 35°F to 338°F. For technicians, the standard threaded stem and rugged die-cast enclosure facilitate straightforward field integration and long-term reliability in mechanical rooms.

• Stainless Steel Trim: Enhanced durability and service life when exposed to high-velocity water or saturated steam.
• Equal Percentage Flow: Delivers precise throttling for superior control of heat exchangers and terminal units.
• Normally Open Fail-Safe: Ensures continuous flow during pneumatic signal failure, protecting critical infrastructure.
• Rugged Bronze Construction: ANSI Class 250 rated body supports high-pressure HVACR applications.
• Field-Proven Actuator: The V-3000 pneumatic actuator provides consistent stem force and reliable spring return.

What is the maximum steam pressure this valve can handle?
This assembly is rated for 100 psig saturated steam, making it suitable for most low-pressure steam heating applications.

Can the actuator action be reversed in the field?
The assembly is factory-configured as normally open; however, the V-3000 actuator design allows for field adjustments or replacements to meet specific sequence requirements if needed.

What type of signal is required for operation?
The 9-13 PSI spring range is designed to work with standard pneumatic controllers and 3-15 PSI instrumentation signals.
