The HERION 8026570 is a high-performance 3/2 way NAMUR interface solenoid valve designed for the control of pneumatic quarter-turn or linear actuators. Manufactured by IMI Norgren under the Herion brand, this valve features a direct NAMUR mounting pattern, simplifying installation and reducing the need for extra fittings. It operates as normally closed (NC) with spring return and is commonly used in process automation applications requiring reliable switching of pneumatic actuators. Note: This part number typically refers to the valve body only; the solenoid coil and electrical connector must be ordered separately based on specific voltage and connection requirements.
