New Original SMC SQ2131N-5-C6-Q 5-Port Solenoid Valve
1. Product Overview
The SQ2131N-5-C6-Q is an original SMC 5-port 2-position single solenoid directional control valve belonging to the SQ2000 plug-in cassette series. Designed for high-speed, high-frequency switching applications in compact automation systems, this pneumatic valve adopts rubber seal structure with built-in one-touch push-in ports for 6 mm outer diameter pneumatic tubing. Powered by DC24V solenoid coil, it switches compressed air flow paths to drive small pneumatic cylinders, air grippers and other pneumatic actuators widely used in electronic assembly equipment, packaging machinery, testing fixtures, conveyor sorting systems and precision automated workstations. Its modular plug-in manifold design enables flexible station expansion, low power consumption and ultra-fast response speed, meeting long-cycle continuous operation requirements of modern miniature pneumatic control systems.
2. Main Functions
- Pneumatic flow direction switching: As a standard 5/2 way single solenoid spring return valve, it switches air channel to extend and retract pneumatic actuators; internal return spring resets spool automatically once electrical signal is cut off.
- Low-power electromagnetic driving: Only 0.4W power consumption for DC24V coil, effectively reducing overall power load of control cabinets.
- Built-in push-in tube connection: C6 specification integrated 6 mm one-touch ports realize tool-free quick tubing assembly and disassembly.
- Manual override function: Non-locking push manual button supports on-site commissioning and cylinder action testing without power supply.
- Modular manifold stacking: Multiple valves can be combined on shared DIN rail manifold base to realize centralized air supply and wiring arrangement.
- Stable air exhaust control: Independent exhaust channels with optional built-in silencer reduce operation noise during frequent switching.
- Reverse polarity protection: Internal circuit design prevents coil burnout caused by incorrect DC wiring on industrial sites.
