Overview
The MAC Valves TM-DDAJ-1DA is a 24VDC solenoid pilot valve designed for applications requiring precise pressure control and consistent actuation in pneumatic systems. This valve is part of MAC’s extensive Series 82 solenoid valve family, engineered for industrial automation, process control, and pneumatic circuit applications where reliability and compact design are essential. Operating at 25–150 PSI, the TM-DDAJ-1DA delivers repeatable performance in both on/off switching and proportional control roles.
