The Asco 8344G070 Solenoid Valve (8344G70) is a robust, pilot-operated piston/poppet valve designed for high-flow applications with air or water. This model is available in single or dual solenoid configurations, with the dual solenoid version capable of maintaining position even during power loss. It is ideal for applications requiring consistent, high-volume flow control.
