SY Series Pilot Operated 5-Port Solenoid Valve

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH SY series is mainstream pilot-operated 5-port solenoid valve, featuring ultra-compact body, ultra-low power consumption and greatly upgraded flow capacity. It serves as the core directional control component for cylinder reciprocation and pneumatic circuit switching on all automated production equipment, fully interchangeable with original SMC SY series.

Structural & Core Performance Advantages

  1. Quick Plug-In Manifold Mount Structure

     -- Directly snap onto SS5Y series manifold base, fast assembly and disassembly, easy single-valve maintenance without dismantling the whole valve island.

  2. Ultra-Low Energy-Saving Coil

     -- Optional 0.1W low-power coil, low heat generation, perfectly suitable for long-term continuous energized working conditions, greatly cutting factory compressed air & power cost.

  3. Greatly Optimized High Flow Runner

     -- Internal streamline optimized design, flow capacity increased by about 80% compared with old-generation solenoid valves, realizing faster cylinder extension/retraction speed without pressure loss.

  4. Built-In Pilot Filter Screen

     -- Integrated tiny filter mesh on pilot valve inlet to block dust and impurities, effectively reducing spool jamming failure rate and extending service life.

  5. Multi-Directional Flexible Port Layout

     -- Air ports available on side / top / bottom three directions, freely adjust tubing routing to avoid mechanical interference inside compact equipment frames.

  6. Modular Valve Island Integration

     -- Perfectly matched with SS5Y3 / SS5Y5 / SS5Y7 / SS5Y9 series multi-station manifold bases, realize centralized unified air supply & exhaust, tidy wiring layout and save cabinet installation space.

Complete Model Coding Rule (Example: SY5120-5LZD-01)

  1. SY: Series code of pilot operated 5-port solenoid valve

  2. 5: Size series number (5 = SY5000 medium series)

  3. 1: Circuit function code

     1 = 5/2 single coil spring return;

     2 = 5/2 double latching coil;

     3 = 5/3 three-position valve

  4. 2: Internal structural base code

  5. 0: Standard base mounting type

  6. 5: Coil voltage code (5 = DC24V, mainstream)

  7. LZ: Socket & protection configuration

     L = L-shaped plug socket; Z = built-in LED indicator + overvoltage protection circuit

  8. D: Manual override code (push-turn locking screwdriver operation)

  9. 01: Port thread size (01 = Rc1/8")

Typical Industrial Application Scenarios

     -- Automated assembly production lines, semiconductor precision equipment, packaging machinery

     -- Automotive stamping & welding production lines, medical testing instruments

     -- Pneumatic robotic grippers, linear slide cylinders, rotary indexing actuators

     -- Cylinder forward/retreat switching, pneumatic circuit on-off and speed regulating control
