SMC SY7340-5DZ Pneumatic Directional Control Valve

The SMC SY7340-5DZ is a 5-port, 3-position closed-center pneumatic directional valve with dual 24 V DC solenoids. It is part of the SY7000 family and is designed for true closed-center operation in a 5-way, 3-position configuration. The valve uses two solenoids to shift between end positions, and is configured for 24 V DC operation. The body is aluminum (die-cast in some variants), with mounting options including base-mount (Base MT) and DIN-compatible configurations. With a flow coefficient (Cv) of about 1.4, it accommodates a range of pneumatic loads, and typical operating pressure ranges from about 0.2 to 0.7 MPa (roughly 29–101 psi), depending on the exact model. Some listings cite a maximum rating near 130 psi for certain configurations. The -DZ suffix denotes the double-solenoid variant of the 5-port SY7000 valve.
