Johnson Controls D-3244-5110 Pneumatic Actuator

The Johnson Controls D-3244-5110 is a high-performance pneumatic actuator specifically engineered for precise modulation of VF Series butterfly valves. This heavy-duty unit is designed to interface seamlessly with 4-inch high-pressure and 5-inch low-pressure valve bodies, ensuring reliable fluid control in demanding industrial and commercial HVAC systems. Operating within a standard 8-13 psi spring range, the D-3244-5110 delivers consistent positioning force to maintain the disc level of the valve against system pressure. Built with a rugged die-cast aluminum housing and a durable synthetic elastomer diaphragm, this Johnson Controls pneumatic valve actuator is designed for longevity in environments ranging from -20 to 150°F. The 4-inch stroke provides the necessary travel for full-port modulation, while the 1/8-inch NPT barbed fitting allows for quick integration with 5/32 or 1/4-inch O.D. polytubing. For contractors seeking a direct field-mount solution, this actuator provides the mechanical advantage and reliability required for critical cooling and heating mechanical rooms.

• Specifically optimized for 4-inch and 5-inch VF Series valves, ensuring perfect mechanical linkage and stroke alignment.
• Features a robust 8-13 psi nominal spring range for stable control and fail-safe operation in pneumatic loops.
• Constructed with a heavy-duty die-cast aluminum body to withstand the rigors of mechanical room environments.
• Utilizes a high-cycle synthetic elastomer diaphragm for consistent response and reduced air leakage over time.
• Universal 1/8-inch NPT barbed air connection simplifies integration with existing pneumatic control systems.

Which valve sizes is the D-3244-5110 compatible with?
