Description
Johnson Controls VG7241ST 2-Way Globe Valve Overview
The Johnson Controls VG7241ST is a heavy-duty, 2-way normally open globe valve engineered for precise flow control in commercial HVAC hydronic and steam systems. Built with a cast bronze body and brass trim, this valve delivers long-lasting corrosion resistance and reliable performance in demanding building automation and mechanical room environments.
Key Features
- 2-way, normally open (NO) configuration for fail-safe operation
- 2-inch NPT end connections for straightforward threaded installation
- 46.2 Cv flow coefficient for high-capacity flow management
- Equal percentage flow characteristic for accurate, linear control response across the full stroke range
- Cast bronze body construction for superior corrosion resistance and durability
- Brass trim components for compatibility with a wide range of hydronic media
- Standard threaded stem design for compatibility with a broad range of Johnson Controls actuators
- Push-down-to-close (PDC) stem action for predictable, consistent valve positioning
Construction & Design
The VG7241ST features a globe-style body that provides inherently stable throttling characteristics, making it ideal for modulating control applications. The equal percentage flow characteristic ensures that each increment of stem travel produces a proportional percentage change in flow, enabling tight and responsive control at both low and high flow conditions. The standard threaded stem interfaces directly with compatible Johnson Controls electric or pneumatic actuators.
Typical Applications
- Chilled water and hot water coil control in air handling units
- Fan coil unit (FCU) water flow regulation
- Commercial building automation and DDC control systems
- Hydronic heating and cooling distribution systems
- Terminal unit and zone valve applications
