Description
The Johnson Controls V47AE-1 is a direct acting, temperature actuated water regulating valve engineered for precision flow control in hydronic and HVAC systems. Built with a durable cast iron body and a 1-1/4″ NPT connection, this valve responds directly to temperature changes sensed through its remote bulb and capillary assembly — no external power source required.
Key Features
- Direct acting, temperature actuated operation for reliable, self-contained control
- Cast iron valve body for durability in demanding hydronic applications
- 1-1/4″ NPT inlet/outlet connections for standard piping compatibility
- 75°F to 135°F cross ambient point temperature range for precise sensing
- 6-foot capillary for flexible remote bulb placement
- Style 4 bulb: 11/16″ diameter x 16-1/4″ long for accurate immersion sensing
- 1/2″ NPT external fitting for secure bulb well or immersion installation
