SY5240-5LZ: Pilot-Operated 5-Port Solenoid Valve, Integrated Control Core with Double Solenoid, Low Power Consumption

Product Positioning
The SY5240-5LZ is a pilot-operated 5-port solenoid valve from the SMC SY5000 series, featuring a 2-position double solenoid, base mounted design. This series is centered around its ultra-low power consumption, high integration, and modular installation capabilities, achieving excellent flow performance and energy savings within a compact valve body size. Its extensive manifold options make it an ideal choice for achieving efficient pneumatic control in packaging machinery, electronic assembly, medical devices, and various general automation production lines.

Core Highlights: Ultra-Low Power Consumption, Double Solenoid Memory, Intelligent Indication

• Ultra-Low Power Design for Significant Energy Savings
  • Standard coil power consumption is only 0.35 W (DC24V).
  • Optional energy-saving circuit further reduces holding power to 0.1 W (with power saving circuit), saving approximately 75% energy compared to traditional solenoid valves. It features extremely low heat generation, meeting the demands of high-density installation and significantly reducing overall equipment energy consumption.
• Double Solenoid Design, Maintains Position at Power Off
  • Employs a 2-position double solenoid structure, using two coils to control spool shifting and resetting. The spool position is self-retaining after power-off.
  • Suitable for applications requiring pressure holding after power failure, bistable control, or prevention of unintended resetting, such as clamping and positioning stations.
• High Flow Capacity, Rapid Response
  • The SY5000 series achieves a Cv value of 0.66 in the base mounted type, with a sonic conductance C value of 2.8 dm³/(s·bar).
  • Response time is 22 ms or less, with a maximum operating frequency of 5 Hz, meeting medium to high-speed automation cycle demands.
• Intelligent Indication and Protection, Reliable Electrical Connection
  • “L” in the model indicates an L-type socket lead-out (with 300mm lead wire), standardizing electrical connections for easy plug-in/out.
  • “Z” indicates inclusion of an indicator light and surge voltage protection. The LED indicator shows the operating status in real-time, and the surge protection circuit effectively safeguards the control system from voltage spikes.
  • Manual operation is non-locking push type, facilitating on-site commissioning and emergency manual control.
• Modular Design, Flexible Integration
  • Designed as a base mounted type, it can be used individually or integrated onto a manifold block to form a high-density valve group.
  • 3-port and 5-port valves can be mixed and mounted, greatly enhancing system design flexibility.
  • Various manifold types are available, including aluminum integrated body, DIN rail mount, and combination manifold types. Manifold model numbers: SS5Y3, SS5Y5, SS5Y7, SS5Y9.
• Wide Operating Condition Adaptability, Safe and Reliable
  • Operating pressure range (internal pilot): 0.1 to 0.7 MPa; External pilot: -100kPa to 0.7 MPa (vacuum applicable).
  • Ambient/fluid temperature: -10 to 50°C.
  • Enclosure rating is dust-tight (IP65 for DIN terminal and M8 connector types).
  • Designed for non-lube operation, pre-lubricated at the factory, requiring no additional oiling for long-term operation, reducing maintenance costs.
