Johnson Controls V-4710-601 Diaphragm

The Johnson Controls V-4710-601 is a high-performance replacement pneumatic actuator diaphragm specifically engineered for 6-inch diameter 3R series actuators. Designed to maintain precise control in commercial HVAC systems, this synthetic rubber diaphragm facilitates the conversion of pneumatic pressure into mechanical force, driving the stroke of your V-3000 series or 3R valve assemblies. Its robust construction ensures reliable actuator travel and sensitive response to branch line pressure changes from a controller or transducer. As a critical repair part, the V-4710-601 allows technicians to restore full torque output and operational calibration without replacing the entire actuator housing. This OEM-quality component is essential for maintaining the proportional control of steam, hot water, or chilled water valves in demanding building automation environments. Regular inspection and replacement of the diaphragm are recommended to prevent air leaks and ensure the long-term efficiency of your Johnson Controls pneumatic actuator system.

• Precise Compatibility: Custom-fit for 6-inch 3R actuators, ensuring a perfect seal and optimal force output.
• System Efficiency: Restores factory-standard pneumatic response, reducing air loss and optimizing energy consumption.
• Durable Construction: Engineered to withstand the thermal and mechanical stresses of HVAC valve modulation.
• Cost-Effective Maintenance: Simplifies field repairs by allowing for unit-level diaphragm replacement rather than complete assembly swaps.

• When should I replace my V-4710-601 diaphragm? Replace if you notice sluggish valve response, audible air leaks at the actuator, or if the actuator fails to reach full stroke at max pressure.
• Is this compatible with 4-inch actuators? No, this specific model is sized exclusively for 6-inch diameter 3R actuators.
• Does this include the actuator mounting hardware? This part number is for the replacement diaphragm only; existing hardware should be reused or sourced separately.
