Johnson Controls VG7241RT+3003E Valve Assembly

The Johnson Controls VG7241RT+3003E is a heavy-duty 2-way normally open globe valve assembly engineered for precise modulating control in commercial HVACR systems. Built with a 1 1/2 inch NPT threaded connection, this unit features a rugged cast bronze body and reliable brass trim, making it ideal for regulating hot water, chilled water, or 38 psig saturated steam. The integrated spring return pneumatic actuator utilizes a 9-13 psi spring range to ensure a fail-safe open position, providing a 28.9 Cv flow coefficient with an equal percentage flow characteristic for stable heat transfer across various load conditions.

Designed for professional contractors, this VG7000 series valve meets ASME B16.15 Class 250 specifications, handling fluid temperatures ranging from 35°F to 284°F. The V-3000 series actuator includes a replaceable synthetic rubber diaphragm housed in a die-cast aluminum enclosure, protecting internal components from site debris. This assembly is a direct solution for field replacements or new installations requiring high-capacity flow control and proven pneumatic reliability in air handling units and heat exchangers.

• Optimized Flow Control: The 28.9 Cv rating and equal percentage plug design provide superior linear heat output in water and steam applications.
• Fail-Safe Operation: The normally open configuration with a 9-13 psi spring return ensures the valve defaults to the open position upon loss of control air.
• Robust Construction: A cast bronze body and self-adjusting packing offer long-term performance under high-pressure conditions up to 300 psi at 150°F.
• Standardized Fit: 1 1/2" NPT female connections allow for seamless integration into existing threaded piping systems.

What media is this valve assembly compatible with?
This assembly is designed to handle hot water, chilled water, and saturated steam up to 38 psig. It is also compatible with water and glycol solutions up to 50% concentration.

Can the V-3000 actuator be serviced in the field?
Yes, the synthetic rubber diaphragm and the internal spring kit are replaceable, allowing for maintenance without necessarily removing the entire valve body from the line.

Is a pilot positioner required for this model?
While not included, this enclosed pneumatic actuator can be used with a V-9502 pilot positioner if your application requires increased force or specific sequencing.
