【English Product Introduction】
The 4A230-08 three-position five-port double air pilot valve is a core control component designed for industrial pneumatic systems, particularly suitable for automation scenarios requiring precise airflow direction switching and center position blocking functionality. Utilizing dual pneumatic signal control, the valve achieves three-position switching (left, center, right) through pressure variations at external pilot ports, meeting diverse operational requirements including equipment start-stop control and actuator reciprocating movements.
Constructed with high-strength engineering materials, the valve features precision-machined spool components that effectively reduce friction loss. Combined with specialized sealing technology, it ensures stable operation within a wide pressure range of 0.15-0.8MPa. Five standardized pneumatic ports (1 supply, 2 working, 2 exhaust) support multiple piping configurations for easy system integration. The center position blocking function reliably maintains actuator position to prevent unintended movement.
This valve demonstrates excellent environmental adaptability, operating within medium temperatures of -5℃ to 80℃, with protection level meeting general industrial requirements. Its compact design optimizes installation space efficiency, while modular construction simplifies maintenance. Typical applications include injection molding machines, packaging equipment, material handling systems, and automated production lines, particularly excelling in scenarios requiring pressure retention at neutral position or emergency stop functions.
