Description
The Schneider Electric (Barber Colman) PNV-202 is a 9-inch replacement diaphragm engineered for use with MK-66xx, MK-68xx, and MK-88xx series pneumatic valve actuators. Designed as a direct OEM-compatible replacement, this diaphragm restores proper sealing and actuation force to your pneumatic control valves, helping maintain precise flow control in commercial HVAC and building automation systems.
Pneumatic actuator diaphragms are critical wear components — over time, exposure to compressed air cycling and environmental conditions can cause cracking, stiffening, or loss of flexibility, leading to actuator drift, poor valve positioning, or complete loss of control. Replacing the diaphragm with the correct OEM-spec PNV-202 ensures your actuator returns to full, reliable operation without the cost of a complete actuator replacement.
