Pump mounted 3 position 3 way valve is commonly used with single-acting cylinders for lifting applications or production work. The center position holds the load with the pump motor on or off. The Simplex patented 3 position/3-way, “Suc-O-Matic” Valve draws hydraulic oil out of any single-acting cylinder. In the retract position, the valve generates enough suction to fully retract any single-acting load return cylinder automatically.
  • Fully Retract load return cylinders.
  • Retracts spring return cylinders up to 33% faster.
  • Full retraction regardless of weak springs or mounting.
