Johnson Controls VG7241LT+3008DP Valve Assembly
The Johnson Controls VG7241LT+3008DP is a high-performance 2-way normally open globe valve assembly engineered for precise proportional control in commercial HVACR systems. Built with a heavy-duty cast bronze body and durable brass trim, this 3/4" NPT assembly is designed to regulate hot water, chilled water, and saturated steam up to 15 psig. The 7.3 Cv equal percentage flow characteristic ensures stable modulating performance, preventing hunting in high-demand air handling and terminal unit applications. Actuation is handled by an exposed pneumatic actuator featuring a 4-8 PSI spring range and a factory-integrated V-9502 positioner. This setup provides a 25:1 rangeability and ANSI Class IV shutoff reliability, crucial for maintaining energy efficiency and system balance. The spring return safety function ensures the valve defaults to the open position upon loss of pilot air, protecting downstream equipment from potential freezing or stagnation.
Key Benefits- Optimized Flow Control: The 7.3 Cv rating with an equal percentage curve provides superior modulating control for HVAC water and steam loops.
- Rugged Construction: Features a cast bronze valve body rated for ANSI Class 250, ensuring long-term structural integrity in high-pressure environments.
- Precise Positioning: Includes a factory-mounted pneumatic positioner for accurate stem travel and high-force close-off pressure.
- System Safety: Reliable normally open spring return action provides a failsafe state for critical heating or cooling sequences.
- Field Serviceability: Employs standard ring pack packings for industry-leading life and simplified maintenance during routine inspections.
What is the maximum fluid temperature for this assembly?
The VG7000 series with brass trim is rated for fluid temperatures ranging from 35°F to 250°F, making it suitable for both chilled water and low-pressure steam applications.
Can the actuator be replaced or upgraded in the field?
Yes, the standard VG7000 series globe valve bonnet and stem design allow for easy field retrofitting or replacement of the 3000 series pneumatic actuator using standardized mounting kits.
Is this valve suitable for high-pressure steam?
This specific model with brass trim is rated for saturated steam up to 15 psig. For higher pressure steam requirements up to 100 psig, a stainless steel trim configuration is typically required.
