SMC Corporation VBA2-Y-13 Diaphragm Assembly NSMP

The SMC VBA2-Y-13 Diaphragm Assembly NSMP is a replacement diaphragm module designed specifically for the VBA2-Y-13 booster regulator from SMC. This component provides the flexible membrane inside the regulator that responds to pressure differences to modulate the actuator and control the regulator’s output. Replacing the diaphragm assembly helps restore accurate pressure regulation and consistent response in pneumatic systems that utilize the VBA2-Y-13, ensuring reliable operation without introducing electronic controls. The NSMP designation identifies the exact diaphragm assembly compatible with VBA2-Y-13 installations, helping technicians achieve a proper seal and fit during maintenance. This non-electronic, fluid-pressure–driven part plays a critical role in maintaining stable downstream pressure in applications where precise pneumatic control is essential.
