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
Back-to-back Check/Shuttle

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
