PU220-04 1/2" Direct/Pilot-Operated Brass Solenoid Valve AIRMIXS
The AIRMIXS PU220-04 is a high-performance 2-way pilot-operated solenoid valve engineered for efficient control of air, water, gas, and non-corrosive liquids. Designed with a Normally Closed (NC) configuration, the valve remains closed until energized. It provides high flow rates and reliable switching, making it an ideal solution for industrial fluid automation, water treatment systems, and high-volume pneumatic control circuits.
