The 4A220-08 is a 5-port, 2-position (5/2-way) directional control valve. As a double air-pilot model, it features a "memory" function, meaning the valve stays in its last shifted position even after the pilot signal is removed, until an opposing signal is received.
It is constructed with a high-strength aluminum alloy body and a precision-ground sliding spool that ensures sensitive reaction times and a long service life. The internal ports are specifically processed to reduce friction, allowing the valve to operate efficiently without the need for additional oil lubrication.
