Johnson Controls VG7241LT+3008B Valve Assembly

The Johnson Controls VG7241LT+3008B is a heavy-duty 3/4" NPT valve assembly designed for high-performance fluid control in HVACR systems. This 2-way normally open globe valve features a cast bronze body with brass trim and a standard threaded stem, making it ideal for regulating hot water, chilled water, and saturated steam flow. The unit is factory-mounted with a V-3000-8001 exposed pneumatic actuator, providing a 3-6 psi spring range for precise modulation. With a 7.3 Cv rating and an equal percentage flow characteristic, this assembly ensures stable control even under varying pressure conditions. Built for professional contractors, the VG7000 Series utilized in this assembly is known for its ring pack packings, which offer industry-leading reliability and tight ANSI Class IV shutoff. The spring return safety feature ensures the valve fails to the open position (push-down-to-close) upon loss of pneumatic pressure, protecting critical pneumatic control loops from overheating or freezing.

• Optimized Flow Control: The equal percentage characteristic and 7.3 Cv provide superior throttling for water and steam applications.
• Rugged Construction: Features a cast bronze body and brass seat rated for temperatures up to 248°F (120°C).
• Pneumatic Precision: The V-3000 pneumatic actuator includes a rolling diaphragm for consistent force output and a clear stroke position indicator.
• Field Serviceable: Designed with a standard bonnet and stem for interchangeability of actuators and easy in-place repacking.
• Tight Shutoff: Tested to meet ANSI Class IV standards, ensuring minimal seat leakage and increased energy efficiency.

What media is compatible with the VG7241LT+3008B?
This valve is engineered for saturated steam (up to 35 psig), chilled water, hot water, and 50/50 glycol solutions.

Is the actuator replaceable or interchangeable?
Yes, the VG7000 Series uses a standardized bonnet design that allows for the removal of the exposed pneumatic actuator and replacement with other pneumatic or electric actuators using compatible mounting kits.

How does "Normally Open" affect system safety?
As a Normally Open (N.O.) assembly, the valve remains at full flow until pneumatic pressure is applied. In the event of a control air failure, the spring return mechanism forces the valve to the open position, which is a common requirement for heating coils to prevent freezing.
