System Integration:

• This valve belongs to the Festo Tiger Classic family of directional control valves.

• Electrical actuation requires an F‑series (8mm core diameter) solenoid coil, e.g., MSFG‑24/42‑50/60 (4527, 24V DC / 42V AC).

• Coil mating socket must be ordered separately (DIN 43650‑B / EN 175301‑803).

• Supports manifold mounting on PAL strips or PRS blocks with up to six valve positions.

• For detailed installation drawings, pneumatic circuit diagrams, and wiring, refer to the product hardware manual (Festo catalog sheet, support portal page).
