Overview
The Johnson Controls VG1241FR+928GGA is a factory-assembled actuated valve unit featuring a 2-inch, 2-way forged brass ball valve combined with a VA9208-GGA-2 spring-return electric actuator. This assembly provides precise proportional control for HVAC systems, operating as a normally open (spring open) device that responds to analog control signals to regulate fluid flow effectively.
Features
- Forged brass body provides a high static pressure rating of 580 psig.
- Chrome-plated brass ball and nickel-plated brass stem assembly ensure durable operation.
- Graphite-reinforced polytetrafluoroethylene (PTFE) seats offer excellent wear resistance.
- High rangeability of 500:1 delivers exceptional control under all load conditions.
- Maintenance-free design is rated to perform for over 200,000 full stroke cycles.
