Johnson Controls V-4710-604 Diaphragm

The Johnson Controls V-4710-604 Diaphragm is a professional-grade 16-1/2" diameter replacement diaphragm specifically engineered for high-capacity 8R series pneumatic valve actuators. Designed for heavy-duty HVACR applications, this synthetic elastomer diaphragm ensures precise pressure regulation and reliable fluid flow control in large-scale systems. It is the critical component used to convert compressed air pressure into the mechanical force required to operate the actuator arm on V-5210 series normally open valves, typically ranging from 2-1/2" to 4" in size. As a veteran-preferred pneumatic actuator part, it offers the structural rigidity and resilience needed to maintain HVAC valve timing and operational efficiency in high-flow environments. This genuine Johnson Controls OEM part provides a direct fit for the 16-1/2 inch 8R housing, eliminating the need for field modifications and ensuring that your pneumatic control system maintains factory-specified calibration and stroke performance under standard operating loads.

• System Compatibility: Precision-molded for the 16-1/2 inch 8R series actuator typically found on V-5210 series valve assemblies.
• Industrial Durability: Manufactured from high-quality synthetic elastomer to withstand the rigorous cycling and pressure fluctuations of industrial HVAC systems.
• Mechanical Response: Facilitates an immediate and accurate conversion of pneumatic signals to mechanical motion for tight valve seating and modulation.
• Direct OEM Replacement: Ensures full adherence to original equipment specifications, maintaining actuator stroke accuracy without compromising flow rates.

Common Questions

Which valve series is the V-4710-604 compatible with?
This diaphragm is primarily utilized with 8R actuators installed on Johnson Controls V-5210 series valves, specifically those in the 2-1/2" through 4" size range for reliable pneumatic control.

What material is used in the construction of this diaphragm?
It is constructed from a robust synthetic elastomer or high-grade rubber designed to resist the wear and thermal stresses common in pneumatic HVAC systems.

Does this diaphragm fit 5R or smaller actuators?
No, the V-4710-604 is specifically sized at 16-1/2" inches for the 8R actuator and is not interchangeable with smaller 5R or No. 4 actuator components.
