SUN HYDRAULICS part description

The single ball shuttle connects the higher of two work ports to the signal or common port. The signal is sensed at port 3.

  • Shuttle cartridges feature hardened steel balls and seats for excellent wear characteristics and contamination tolerance.
  • The single ball allows for the decay of the pressure signal when both load ports drop to a lower pressure.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
