Description
The Schneider Electric (Barber Colman) PNV-2 is a genuine OEM replacement diaphragm designed for use with MK-4xxx Series pneumatic valve actuators. Engineered to restore original performance and reliability, this diaphragm is an essential service part for maintaining the integrity of your pneumatic control system.
Product Overview
Pneumatic valve actuators depend on a properly functioning diaphragm to accurately translate air pressure signals into precise valve movement. Over time, diaphragms can wear, crack, or lose flexibility — resulting in sluggish response, air leakage, and loss of control accuracy. The PNV-2 diaphragm provides a direct, factory-specified replacement to bring your MK-4xxx Series actuator back to full operating specification.
