Pneumatic Solenoid Valve 820 Series: NC 2/2 Type ,Research into materials and new technological solutions has enabled the realization of a shutter solenoid valve within the 820 Series. Its operating principle is extremely simple, yet it boasts cutting-edge dynamic performance. The mass of the moving components has been minimized, and all internal friction has been eliminated. Through this approach, we have achieved millisecond-level response times and an operational lifespan exceeding 500 million cycles.
