Description
The Johnson Controls V47AB-5 is a direct acting, temperature actuated water regulating valve engineered for precise hydronic and HVAC system flow control. Built from durable cast brass, this valve responds directly to temperature changes sensed through its remote bulb and capillary assembly — requiring no external power source for operation.
Key Features
- Direct acting, temperature actuated operation — no external power required
- Cast brass valve body for long-lasting corrosion resistance and durability
- 1/2″ NPT inlet and outlet connections for straightforward installation
- 75°F to 135°F cross ambient point temperature sensing range
- 6-foot capillary tube for flexible remote bulb placement
- Style 4 sensing bulb: 11/16″ diameter x 10″ long for accurate immersion sensing
- 1/2″ NPT external fitting for secure bulb well or immersion installation

The V47AB-5 is ideal for applications where water flow must be regulated in response to system temperature — such as condenser water circuits, chiller systems, and hydronic loops. The remote bulb senses fluid temperature and mechanically modulates the valve to maintain setpoint conditions, delivering reliable and energy-efficient performance without the need for electrical controls.
