Johnson Controls VG7241ES Valve

For veteran HVACR technicians and building automation contractors, the Johnson Controls VG7241ES is a foundational component for precision hydronic and steam regulation. This 1/2 inch 2-way globe valve is engineered with a normally open configuration and a push-down-to-close action, ensuring reliable flow control in various terminal unit applications. Built with a high-durability cast bronze body and brass trim, this valve is rated for ANSI Class 250 service, making it capable of handling hot water, chilled water, and saturated steam up to 35 psig.

The VG7241ES features an equal percentage flow characteristic and a 1.8 Cv rating, providing the granular control necessary for maintaining stable discharge air temperatures. Its slotted stem and small bonnet design are specifically optimized for seamless integration with VA-7310 electric actuators and V-3801 pneumatic actuators. With a threaded NPT connection and the industry-standard Johnson Controls Ring Pack packing, this valve minimizes leak paths and simplifies field maintenance, ensuring long-term operational efficiency in demanding mechanical environments.

Key Benefits:

• Precise Modulation: The 1.8 Cv equal percentage response ensures accurate flow management for heating and cooling coils.
• Rugged Construction: ANSI Class 250 cast bronze housing provides superior pressure and temperature resilience for water and steam.
• Flexible Actuation: Standardized slotted stem design allows for quick field mounting of both electric and pneumatic control heads.
• High-Side Reliability: Rated for fluid temperatures ranging from 35?F to 248?F, covering the bulk of standard HVAC applications.
• Low Leakage: Tight shutoff characteristics (ANSI Class IV) ensure energy conservation and prevent "creep" during off-cycles.

Common Questions:

What is the maximum static pressure for the VG7241ES?
This valve is designed for ANSI Class 250 service, which typically supports a maximum static pressure of 400 psi at standard operating temperatures.

Which actuators are compatible with this specific slotted stem model?
The VG7241ES is purpose-built for use with Johnson Controls VA-7310 series electric and V-3801 pneumatic actuators using the small bonnet mounting profile.

Can this valve be used for steam applications?
Yes, this bronze globe valve is suitable for saturated steam services up to 38 psig, provided the paired actuator is rated for the environment.
