Johnson Controls VG7441ST Valve

The Johnson Controls VG7441ST Valve is a 2-inch normally closed globe valve engineered for precision control of hot water, chilled water, and steam in demanding commercial HVAC systems. This 2-way NPT control valve features a rugged cast bronze body and brass trim, providing long-term durability and resistance to scaling. With a 46.2 Cv flow coefficient and an equal percentage flow characteristic, it ensures high-rangeability and accurate modulation across varying demand levels. Designed with a push down to open action and a standard threaded stem, the VG7441ST is compatible with a wide array of Johnson Controls pneumatic and electric actuators, including the M9000 and VA-7000 series. This valve assembly meets ANSI Class 250 pressure ratings, making it a reliable choice for contractors managing high-pressure hydronic systems. Whether you are replacing an existing unit or performing a new installation, this Johnson Controls VG7000 series body offers the professional-grade performance and exact fit required for critical climate control applications.

• Bronze and Brass Construction: Heavy-duty cast bronze body with durable brass internal components for extended service life in water and steam loops.
• Wide Compatibility: Standard threaded stem design allows for seamless field or factory assembly with numerous actuator types.
• High Temperature Range: Rated for fluid temperatures ranging from 35°F to 284°F, suitable for both chilled water and low-pressure steam.

Common Questions

Is the VG7441ST suitable for steam applications?
Yes, this valve is rated for use with steam up to certain pressure limits when paired with a compatible actuator. It is typically utilized for low-pressure steam control in HVAC radiators and heat exchangers.

What is the fail-safe position for this valve?
The VG7441ST is a normally closed valve with a push down to open (PDTO) action. The specific fail-safe position (open or closed during power loss) will depend on the spring-return orientation of the actuator installed on the valve body.

Can I repack the stem without removing the valve from the line?
Yes, the VG7000 series is designed for serviceability, allowing for in-place valve repacking to minimize system downtime for contractors.
