SMC Corporation VQC4201-5 Solenoid Valve 4 Way

SMC VQC4201-5 is a 4-way, 5-port base-mounted solenoid valve in the VQC4000 family, engineered for compact pneumatic control in automation systems. The valve is a 2-position, 4-way unit with base mounting and plug-in compatibility, offering direct flow paths between actuator ports A and B with dedicated exhausts. Key specifications include a working pressure range of 0.15 to 1 MPa and a Cv flow coefficient of 2.1, with maximum flow up to around 4,350 L/min depending on supply and load. Coil configurations vary by variant: standard versions typically draw about 0.95 W, while low-wattage types use around 0.4 W, with 24 V DC coil voltage common in dual-solenoid assemblies. The body is designed with a compact pitch of 25 mm or 41 mm to suit tight spaces, and the valve supports base mounting with plug-in sub-plates for easy integration into panels. Some configurations include a light/surge voltage suppressor for transient protection. Typical applications include pneumatic control for double-acting cylinders and general 4-way valve duties in automation lines and manufacturing equipment.
