SMC
$47.65
The SMC SY3140-5LZ is a 5-port, 2-position single solenoid valve from the SY3000 series, used to control the direction of air flow to double-acting pneumatic actuators. As a single-solenoid, spring-return valve, it shifts when energized and returns to its default position when de-energized. It runs on 24 VDC with a power consumption of just 0.1 W thanks to the built-in power-saving circuit, and includes a built-in light and surge voltage suppressor to protect PLC outputs.
Configuration: SY3000 series • 2-position single • internal pilot • 24 VDC • L-type plug connector with 300 mm lead wire • light/surge voltage suppressor • push-turn locking manual override • base mounted, supplied without sub-plate.
Key Features
- 5-port, 2-position single solenoid (5/2) directional control for double-acting cylinders
- Low power consumption of 0.1 W with power-saving circuit
- 24 VDC rated coil with internal pilot operation
- L-type plug connector pre-wired with a 300 mm lead wire
- Built-in light and surge voltage suppressor protects driving circuitry
- Push-turn locking manual override for safe setup and troubleshooting
- Base-mounted design compatible with SS5Y3 manifolds or an individual sub-plate
- Mixed mounting of 3-port and 5-port valves possible on common manifolds

Typical Applications
- Directional control of double-acting pneumatic cylinders
- Automated assembly, packaging, and material-handling machinery
- Manifold-mounted valve banks driving multiple actuators from one PLC
- Machine tending and pick-and-place actuation
- Compact pneumatic circuits where low power draw and space savings matter
Mounting, Sub-plates & Accessories
This valve is supplied without a sub-plate. To pipe it as an individual valve, add a sub-plate; to run several valves together, mount them on an SS5Y3 series manifold. Compatible SMC accessories for the SY3000 series include:
- Sub-plate: SY3000-27-1
- Gasket: SY3000-11-25
- Mounting screw: SY3000-23-4 (round head combination screw)
- Manifolds: SS5Y3 series (aluminum body, DIN rail, and stacking types available)
