Sun Hydraulics offers a variety of two-, three- and four-port shuttle cartridges. All shuttle cartridges operate at pressures up to 5000 psi (350 bar).

  • Single ball shuttles with or without an external port in the hex of the cartridge
  • Back-to-back check cartridges with or without an external port in the hex of the cartridge
  • Low side (hot oil) shuttles for hydrostatic transmissions
  • High side blocked center shuttles
  • High side spring offset 2-position, 2-way shuttles

Single Ball Shuttle

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = 5 drops/min.

Single Ball Shuttle Valve with Signal at Port 3 or Port 2

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = 5 drops/min.

Back-to-back Check/Shuttle

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = 5 drops/min.
  • The back-to-back checks do not provide a means of lowering a signal. They will trap a high signal if the load pressures drop to a lower pressure. Some means of bleeding off the signal should be provided.
  • 15 psi check

Low Side, 3-position, Hot Oil Shuttle Valve

  • Maximum operating pressure = 5000 psi
  • Pilot flow = DSCH, DSEH: 23 in³/min., DSGH, DSIH: 46 in³/min. (Port 2 and 4 to Port 3).
  • Note: Low shift values can potentially result in charge pump pressure alone inadvertently shifting the valve. Use care when selecting shift pressure.
  • Pressures on Ports 2 and 4 must equalize before reversed shift can take place.

High Side, 3-position, Shuttle Valve

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = DSCS: 2 in³/min. at 1000 psi, DSES: 3 in³/min. at 1000 psi, DSGS: 4 in³/min. at 1000 psi, DSIS: 5 in³/min. at 1000 psi

Spring Offset, 2-position, High Side Shuttle

  • Maximum operating pressure = 5000 psi
  • Minimum pilot pressure required to shift valve = C Range: 30 psi, E Range: 75 psi
