Johnson Controls VG7241PT+3008B Valve Assembly

The Johnson Controls VG7241PT+3008B is a professional-grade 1 1/4" NPT pneumatic globe valve designed for precise modulation of hot water, chilled water, or steam in demanding commercial HVAC systems. This 2-way normally open valve assembly features a rugged cast bronze body and reliable brass trim, engineered to handle a maximum flow coefficient of 18.5 Cv. The normally open (NO) configuration ensures a fail-safe open position, maintaining system flow upon loss of pneumatic signal.

Integrated with the V-3000-8012 exposed pneumatic actuator, this assembly operates within a 3-6 psi spring range, providing consistent equal percentage flow characteristics for stable temperature control. The spring return pneumatic actuator is built for high-cycle longevity and is suitable for HVAC control valve applications requiring NPT threaded connections. This unit is an essential Johnson Controls valve assembly for technicians looking for a drop-in 1.25-inch replacement that meets ANSI Class IV leakage standards, ensuring efficient pneumatic valve automation and minimal energy waste in hydronic or steam loops.

• Durable Construction: The cast bronze body and brass trim provide excellent corrosion resistance in water and low-pressure steam applications.
• Fail-Safe Logic: Normally open (NO) design ensures safety by allowing full flow if the control signal is interrupted.
• Precise Modulation: Equal percentage flow characteristics offer stable control throughout the entire stroke of the globe valve.
• High Flow Capacity: A 18.5 Cv rating supports significant fluid volume for medium-sized HVAC zones and equipment.
• Serviceable Design: The exposed yoke allowed for straightforward field maintenance and actuator adjustment.

What is the maximum pressure rating for this valve?
This Johnson Controls VG7000 series valve is typically rated for up to 400 psi for water and 35 psi for saturated steam with brass trim. Always verify specific system pressures against the factory submittal.

Can I use this for glycol-based systems?
Yes, this assembly is compatible with water and glycol solutions up to a 50% concentration, making it ideal for chilled water applications.

Does this assembly include the pneumatic actuator?
Yes, the VG7241PT+3008B comes as a complete factory-mounted assembly with the V-3000-8012 pneumatic actuator and the 3-6 psi spring return mechanism.
