SMC Corporation VQC4101-51 Solenoid Valve 3/2 Way

The SMC VQC4101-51 is an electrically actuated 3/2-way solenoid valve from SMC Corporation. It regulates compressed air in pneumatic circuits by switching airflow across three ports in two distinct positions, enabling simple on/off control of a connected actuator such as a pneumatic cylinder. The VQC4101-51 designation identifies the exact valve configuration within SMC’s VQC line, which is used where electrical control of air flow is required. This model provides the essential function of directing supply pressure to the actuator while venting the opposite path, allowing rapid actuation in automation tasks. Designed for integration into standard pneumatic control systems, it supports straightforward connection to control electronics and manifolds that handle compressed air distribution in manufacturing, packaging, and process automation environments. Because it is a solenoid valve, actuation is achieved by energizing the coil to shift the internal element between two positions, eliminating the need for mechanical linkages in the control loop.
