SMC SY7440-5LZE-03 Industrial Pneumatic Solenoid Valve

SMC SY7440-5LZE-03 is a dual-solenoid, 4/5-port SY7000-series pneumatic valve designed for compact, high-speed air switching in automation systems. It operates from a 24 V DC coil (base mounted with a 300 mm lead wire) and Rc-threaded ports, without requiring a bracket, with a 3-position exhaust-center actuation suitable for precise control of pneumatic actuators in tight spaces. The valve supports internal pilot operation from 0.1 to 0.7 MPa and external pilot operation from −100 kPa to 0.7 MPa (pilot range 0.25–0.7 MPa), and provides Cv values of 0.59 (body ported, 10.6 mm²) and 0.7 (base mounted, 12.6 mm²). Expect a response time of 32 ms or less at 0.5 MPa without an indicator light or surge suppressor, a 50°C ambient/fluid temperature rating, and optional surge suppression with a light indicator; it uses L-plug electrical entry and is manufactured in Japan as part of the SY7000 family for base-mount installation in compact machines and pneumatic control panels.
