The CKD 4GD/ER Series where 4GD210 belongs takes 210 (5/2 single solenoid with base) as the core, and derives five categories:
219 (without base), 220 (double solenoid), 310/320 (3/2-way), R (return), EX (explosion-proof).
It covers full port sizes: Φ4–Φ8 push-in, M5–Rc1/4 thread,
and full voltage ratings: CC 12 V/24 V., AC100V/220V,
meeting requirements from general industrial to explosion-proof and integrated applications.
