SMC Corporation SY3440-5LZ 5 Port Solenoid Valve 3-Position Exhaust Center 24V DC Coil

The SMC SY3440-5LZ is a five-port, three-position solenoid valve in the SY3000 family designed for base-mounted installation in compact pneumatic systems. It uses double solenoid actuation with a 24 V DC coil, providing independent control of the valve's two shift functions while the center position exhausts all working ports for a defined rest state. As a five-way, three-position valve configured with an exhaust-center arrangement, it routes compressed air from the supply to one or both work ports while venting others to exhaust, enabling precise extend/retract cycles for connected cylinders. Built for industrial automation, this base-mounted model is compatible with standard SY-series manifolds and applications such as pick-and-place, clamping, and sequencing in packaging lines and material-handling equipment. Key specs include five ports, three positions, exhaust-center operation, base-mounted construction, and dual 24 V DC solenoids for reliable, fast actuation in compact footprints.
