Description
The Schneider Electric (Barber Colman) PNV-102 is a genuine OEM replacement diaphragm engineered for use with the MK-2690 pneumatic actuator. Designed to restore reliable, accurate pneumatic actuation in commercial HVAC and building automation systems, this diaphragm ensures your pneumatic controls continue to operate at peak performance.
Product Overview
Pneumatic actuators depend on a properly functioning diaphragm to convert air pressure signals into precise mechanical movement. Over time, diaphragms can wear, crack, or lose flexibility — resulting in sluggish response, control drift, or complete actuator failure. The PNV-102 provides a direct OEM-matched replacement, eliminating guesswork and ensuring a proper fit with the MK-2690 actuator assembly.
