Overview
The ASCO 8345-03-01 is a compact, 4-way pilot-operated solenoid valve engineered for general service applications requiring low-flow control across pressurized systems. This model features 10-150 PSI operating range and is commonly deployed in pneumatic control circuits, hydraulic valve manifolds, and low-flow fluid distribution systems. The valve delivers dependable on-off or proportional flow control in analytical equipment, heating systems, and process automation.
