Description
The Johnson Controls V-4710-604 is a precision-engineered replacement diaphragm designed for use with 16-1/2″ diameter 8R pneumatic actuators. Keeping your actuator’s diaphragm in peak condition is critical to maintaining accurate valve positioning, consistent flow control, and reliable system performance in commercial HVAC and building automation applications.
Product Overview
This OEM-quality diaphragm is the correct replacement part for Johnson Controls 8R series actuators with a 16-1/2″ diameter housing. When a diaphragm wears, cracks, or loses elasticity, actuator response becomes erratic and control precision suffers. Replacing it with the V-4710-604 restores full pneumatic stroke and sealing integrity, extending the service life of your actuator assembly.
