D-3246-5110
The Johnson Controls D-3246-5110 Pneumatic Actuator is designed for the VF series of HVAC equipment to give precise control of the airflow and temperature. This actuator employs pneumatic force to change the valve position in response to system requirements, with a pressure range of 8-13 PSI. Due to the reliable pneumatic actuation, this device enhances the general stability and performance of HVAC systems. It is well suited for use in air conditioning, heating, ventilating, and refrigerating practices where close control of the flow of liquid or air is required. This is because the design of the actuator allows for a long duration and smooth operation, which also reduces the costs of maintenance and time taken.

Specifications

  • Pressure Range: 8-13 PSI
  • Actuation Type: Pneumatic
  • Weight: 18.17lbs

Product Overview:
Positions the valve disc in Johnson Controls VF Series butterfly valves in response to a pneumatic control signal. The Johnson Controls D-3246-5110 is an OEM pneumatic actuator with an 8–13 psig spring range, designed to convert changes in control-air pressure into mechanical movement at the connected valve. This operation supports controlled fluid flow through HVAC piping systems by adjusting the butterfly valve's position according to the pneumatic control demand.

Pressure Control:
Converts pneumatic pressure of 8–13 PSI into mechanical movement through the actuator's internal pressure-responsive mechanism. This movement drives the connected VF Series butterfly valve in response to changes in the pneumatic control signal.

Valve Position:
Provides actuator movement to the connected butterfly valve to adjust its opening and regulate fluid flow. As pneumatic pressure changes, the actuator moves the valve to adjust flow through the connected system.

Replacement Guidelines:
Replace the Johnson Controls D-3246-5110 Pneumatic Actuator when inspection and functional testing confirm that it can no longer position the connected valve reliably. Replacement may be necessary if the actuator fails to respond to pneumatic pressure changes, cannot complete its required movement, or has a damaged diaphragm, housing, or air connection. Have a qualified HVAC controls technician inspect the actuator and valve assembly and handle pneumatic testing and replacement.

Common Failure Symptoms:

  • Valve fails to move in response to pneumatic pressure.
  • Valve position remains unchanged during control adjustments.
  • Actuator movement becomes slow or inconsistent.
  • Air leakage affects actuator operation.
  • Visible deterioration affects the actuator assembly.

Equipment Compatibility:
The Johnson Controls D-3246-5110 is an OEM D-3246 Series pneumatic actuator designed for VF Series butterfly valves. The manufacturer's selection chart identifies its applications with 5-inch high-pressure valves, 6-inch high- or low-pressure valves, and 8- or 10-inch low-pressure valves. Confirm the valve size, pressure configuration, mounting arrangement, and required actuator action against the equipment documentation before installation.

Customer Questions
What is the Johnson Controls D-3246-5110 pneumatic actuator used for?

It positions the disc of a VF Series butterfly valve in response to a pneumatic control signal, helping regulate flow through the connected system.

How does the 8–13 PSI spring range affect actuator operation?

The spring range identifies the pneumatic pressure range associated with the actuator's operating response and is an important control characteristic when selecting an actuator.

Does this actuator include a pneumatic positioner?

No. The D-3246-5110 is the actuator model without the D-9502 positioner. The corresponding D-3246-5100 model is listed with that positioner.

What should be inspected during pneumatic actuator maintenance?

Inspect the actuator housing, diaphragm assembly, air fitting, and pneumatic tubing for visible damage, deterioration, or air leakage. Check valve movement and actuator response as part of a qualified service inspection.

When should a pneumatic butterfly valve actuator be replaced?

Replacement may be necessary when functional testing confirms that the actuator cannot respond to its pneumatic signal or position the connected valve reliably.
