The EXPFLEX K24R8-L8 and K34R8-L8 products are hand-lever operated pneumatic directional control valves used to manage the flow of compressed air.
These devices are manually controlled by shifting the lever to the left or right, which directs the airflow to move pneumatic cylinders or pistons back and forth. The term "single solenoid" (tek bobin) in your initial query usually refers to electrically controlled models; however, these specific part numbers denote purely mechanical, hand-operated valves.
Part Number Breakdown and Technical Specifications
The product codes indicate the internal structure and technical design of the valves:
  • EXPFLEX: The brand name of the manufacturer.
  • K24R8-L8 (4/2-Way Valve): This valve features 4 ports (1 inlet, 2 cylinder outputs, 1 exhaust) and 2 positions. Shifting the lever forward moves the cylinder all the way out, and shifting it back brings it all the way in. There is no middle stop position.
  • K34R8-L8 (4/3-Way Closed Center Valve): This valve also has 4 ports but features 3 distinct lever positions (Left, Center, Right). When the lever is placed in the center position, all ports are blocked, completely stopping the airflow.
  • 1/4" (R8 / L8): Indicates that the port thread size for the air hose fittings is 1/4 inch (approximately 13mm standard pneumatic fitting thread).
Purpose and Applications
These valves are designed to redirect compressed air in industrial machinery, workshops, and automated production lines.
  • Double-Acting Cylinder Control: Allows operators to manually dictate the stroke direction of a pneumatic piston or mechanism.
  • Operation with K24R8-L8: Shifting the lever immediately fully extends or fully retracts the connected mechanism. It is ideal for quick, decisive open-close operations.
  • Operation with K34R8-L8: Leaving the lever in the center position traps the air inside the system. This allows you to stop and hold a moving cylinder at any intermediate point along its stroke. It is preferred for precise positioning or safety stops.
Common Industries and Use Cases

  • Controlling molds or ejection mechanisms in plastic injection machines.
  • Industrial pneumatic presses, lifting platforms, and clamping fixtures.
  • Material handling, sorting, and conveyor lines driven by air pressure.
  • Hazardous, explosive (Ex-proof), or wet environments where electrical wiring poses a spark risk.
