Key Features and Benefits
Ultra-Low Power Consumption — Direct PLC Drive
The SYJ314M-5G-X123-Q consumes only 0.35 W, enabling direct control by PLC transistor outputs without interposing relays. The low-power pilot solenoid design dramatically reduces self-heating, ensuring consistent reliability and long-term stability during continuous operation.
Ultra-Compact Design for Flexible Layout
Valve body dimensions are just 55 mm × 28 mm × 11 mm, allowing easy integration even in the tightest spaces. Both base-mount (M5 × 0.8 ports) and manifold-mount configurations are supported — the SS5YJ3 manifold accommodates 2 to 20 stations, ideal for centralised multi-valve control.
High-Speed Response for Precision Control
Response time of ≤ 15 ms and maximum operating frequency of 10 Hz meet the demands of high-duty-cycle switching applications. The non-locking push-type manual override button facilitates on-site commissioning and emergency operation.
Lubrication-Free Operation — Lower Total Cost of Ownership
The rubber soft seal design enables reliable operation without oil mist lubrication, reducing dependency on compressed air filtration systems and minimising long-term maintenance costs.
Dust-Proof Construction for Industrial Environments
The dust-proof structure ensures reliable operation in dusty manufacturing environments. CE marking compliance (standard with -Q suffix) meets EU market regulatory requirements.

FAQ
Q: Can the SYJ314M-5G-X123-Q be used in vacuum applications?
The standard SYJ314M-5G-X123-Q uses an internal pilot air supply and is not suitable for vacuum use. For vacuum applications requiring operation down to -100 kPa, please use the external pilot type SYJ314R-5G-M5, which supplies pilot pressure independently from the main valve.
Q: Is this model compatible with manifold mounting?
Yes. All SYJ300 series base-mounted valves support SS5YJ3 manifold configurations with 2 to 20 stations, sharing a common supply and exhaust port for simplified pneumatic piping.
Q: Are indicator light and surge suppression built in?
Yes. The -G suffix variant includes a built-in LED indicator light and diode surge voltage suppressor, enabling direct connection to PLC outputs or relay contacts without external protection components.
