Description
Johnson Controls VG7443ET Globe Valve Overview
The Johnson Controls VG7443ET is a 2-way, normally closed globe valve engineered for precise flow control in commercial HVAC hydronic systems. Built with a cast bronze body and stainless steel trim, this valve delivers reliable, long-lasting performance in demanding heating and cooling applications. Its equal percentage flow characteristic makes it ideal for applications requiring accurate modulating control across a wide range of flow conditions.
Key Features
- 2-way, normally closed (NC) configuration
- 1/2″ NPT end connections for easy installation
- 1.8 Cv flow coefficient for precise flow sizing
- Equal percentage flow characteristic for accurate modulating control
- Cast bronze body for corrosion resistance and durability
- Stainless steel trim for extended service life
- Standard threaded stem design
- Push-down-to-open (PDO) action
Construction & Design
The VG7443ET features a rugged cast bronze body that resists corrosion in hydronic water and glycol systems. The stainless steel trim provides superior wear resistance and maintains tight shutoff over thousands of operating cycles. The standard threaded stem interfaces directly with compatible Johnson Controls VA series actuators, making this valve a versatile choice for building automation and HVAC control applications.
Flow Characteristics
The equal percentage flow characteristic of the VG7443ET ensures that equal increments of valve stem travel produce equal percentage changes in flow. This characteristic is particularly well-suited for heating and cooling coil control, where it provides stable, responsive modulation across varying system pressures and load conditions.
Applications
- Commercial HVAC heating and cooling coil control
- Hydronic heating and chilled water systems
- Building automation and direct digital control (DDC) systems
- Fan coil unit and air handling unit control
- Zone control in multi-zone hydronic systems
