Description
Johnson Controls VG7243PT Globe Valve Overview
The Johnson Controls VG7243PT is a two-way, normally open globe valve engineered for precise flow control in commercial HVAC hydronic systems. Featuring a 1-1/4″ NPT connection and an 18.5 Cv flow coefficient, this valve delivers reliable equal percentage flow characteristics ideal for heating and cooling coil applications where accurate modulating control is essential.
Key Features
- Globe valve, 2-way normally open (N.O.) configuration
- 1-1/4″ NPT threaded end connections
- 18.5 Cv flow coefficient for accurate flow sizing
- Equal percentage flow characteristic for superior modulating control
- Cast bronze body for corrosion resistance and long service life
- Stainless steel trim for enhanced durability and reliability
- Standard threaded stem design
- Push-down-to-close (PDC) actuator action
Construction & Design
The VG7243PT is built with a robust cast bronze body that resists corrosion in hydronic water systems, making it well-suited for both heating and chilled water applications. The stainless steel trim ensures long-term seat integrity and tight shutoff performance. The standard threaded stem is compatible with a wide range of Johnson Controls VA and VB series electric actuators, enabling straightforward integration into building automation and direct digital control (DDC) systems.
Flow Characteristics
The equal percentage flow characteristic of the VG7243PT provides a consistent percentage change in flow per unit of valve travel, making it the preferred choice for coil control applications. This characteristic helps maintain stable loop control across varying system conditions, improving overall system efficiency and comfort.
Typical Applications
- Commercial HVAC hydronic heating and cooling coil control
- Fan coil units and air handling units (AHUs)
- Building automation and DDC control systems
- Variable flow hydronic distribution systems
- Heat exchanger and terminal unit control
