Johnson Controls VG7241GS Valve

The Johnson Controls VG7241GS is a 1/2 inch NPT normally open globe valve designed for precise flow control in commercial HVAC systems. Featuring a 4.6 Cv rating and an equal percentage flow characteristic, this cast bronze globe valve ensures stable performance in hot water, chilled water, or steam applications. The brass trim and stainless steel slotted stem are built to withstand high differential pressures, providing long-term reliability for terminal unit control and air handling systems. This unit utilizes a small bonnet design and a push-down-to-close action, making it compatible with various Johnson Controls electric and pneumatic actuators. Contractors value the 1/2" NPT female-to-female connections for straightforward installation in tight mechanical rooms. When looking for VG7241GS specifications or a 1/2" brass trim globe valve, this model is the standard for maintaining tight shut-off and accurate modulating control in critical hydronic loops.

Key Benefits

• Equal Percentage Contoured Plug: Provides superior throttling control for consistent temperature regulation across varying load conditions.
• Durable Construction: The cast bronze body and brass trim provide high resistance to scaling and corrosion in open or closed loops.
• Compact Small Bonnet Layout: Specifically engineered for installation in confined spaces, such as fan coils and VAV reheat coils.
• Normally Open Configuration: Ensures a fail-safe open position during power loss, facilitating continuous flow in heating or cooling circuits.
• High Steam Rating: Reliable performance for saturated steam applications up to 38 psig, expanding its utility in mixed-use facilities.

Common Questions
