V47AR-1
The Johnson Controls V47AR-1 Temperature Actuated Modulating Valve is a accurate and steady mechanism used at the control of the flow of the fluids in the HVAC systems according to the temperature changes. This valve has a 1-1/2” pipe connection diameter for the flow of water and chemicals and operating temperature of 75°F – 135°F to ensure the system temperatures are well regulated with accurate responsive modulation. This makes this modulating valve appropriate to be used in the temperature controlled systems such as HVAC. It guarantees the reliable functionality of the system by tuning the flow of the fluid in relation to the temperature state indicated. The V47AR-1 enhances comfort and energy productivity as it helps is regulating appropriate temperatures.

Customer Questions
What maintenance is required for the Johnson Controls V47AR-1 Temperature Actuated Modulating Valve?

Inspect the valve regularly for leaks, corrosion, and tight flange connections to ensure stable operation. Clean external surfaces and remove debris buildup around the actuator area. Verify temperature sensing response and recalibrate if drift occurs. Proper maintenance improves modulation accuracy, system efficiency, and prevents unexpected valve sticking or performance loss.

What are common issues with the Johnson Controls V47AR-1 Temperature Actuated Modulating Valve?

  • Valve sticking or failing to modulate smoothly due to scale or debris buildup.
  • Temperature sensing inaccuracies causing improper opening or closing.
  • Leakage at flange connections from gasket wear or improper tightening.
  • Slow response or erratic control due to actuator malfunction or internal wear.

Installation Steps

Step 1: Shut off system power and isolate water lines, then depressurize and drain the circuit completely.

Step 2: Remove the old valve and clean pipe flanges or threaded ends to ensure proper sealing.

Step 3: Install the new valve in correct flow direction using arrow marking and secure all flange bolts evenly.

Step 4: Position sensing bulb properly in the water stream and secure capillary without sharp bends.

Step 5: Restore pressure, check for leaks, and slowly test modulation response under operating temperature.
