Description
The Johnson Controls V-4710-602 is a genuine OEM replacement diaphragm engineered specifically for use with 8-inch diameter 4R series pneumatic actuators. Designed to restore the actuator’s original performance characteristics, this diaphragm ensures reliable and repeatable valve positioning in commercial and industrial HVAC systems.
Pneumatic actuator diaphragms are critical sealing and force-transmission components. Over time, diaphragms can crack, harden, or lose flexibility due to age, pressure cycling, or chemical exposure — leading to actuator drift, loss of stroke, or complete failure. Replacing the diaphragm with a genuine Johnson Controls part is the most cost-effective way to return a faulty actuator to full service without replacing the entire assembly.

Why Choose a Genuine OEM Diaphragm?
Aftermarket diaphragms may not meet the material or dimensional specifications of the original component, leading to premature failure or inconsistent actuator performance. The V-4710-602 is manufactured to Johnson Controls’ exact standards, ensuring compatibility and reliability in critical valve control applications — including air handling units, chilled water systems, hot water systems, and steam valve assemblies.
