Operation

N/A In the dividing mode, ST16-01 divides the input flow on port 3 between ports 2 and 4, based on the specified ratio, regardless of the operating pressure. In the combining mode, the flow from ports 2 and 4 will be combined into port 3. The division or combining will be maintained even if unequal loads are placed on ports 2 and 4.

The ST16-01 provides synchronizing flow in both combining and dividing modes at bottomed conditions in cylinder applications and at stalled conditions in motor applications. This feature is useful in hydraulic circuits that require cylinders to move at the same time. If one cylinder bottoms out first, the opposite cylinder is provided with the synchronizing flow to allow that cylinder to bottom before both cylinders start moving in the opposite direction.

Features

N/A

  • High accuracy operation
  • Low pressure drop
  • Wide flow range down to 25% of nominal flow rating
  • Provides re-synchronizing flow after completion of the actuator cycle
  • All external surfaces zinc-plated
  • Hardened parts to ensure minimal wear and extend service life
  • One-piece body maximizes reliability and minimizes the effect of eccentricity
  • Industry common cavity
