Sun Hydraulics has established a strong foundation for consistently delivering exceptional performance in all aspects of their business. From product design and service delivery, Sun Hydraulics stands out in the industry.

Since the beginning, Sun products have been setting the standard for the screw-in hydraulic cartridge valve industry. Sun’s floating cartridge construction and cavity design approach allows products to operate precisely and reliably at higher pressures and flow rates in the most demanding applications. The generous porting area, coupled with our manifold design and construction techniques, result in integrated packages that can be up to 50% smaller than competitive offerings.

Sun cartridge valves are offered in five primary sizes, with flow capacity and controlled horsepower doubling with each successive size. Within each broad functional area (pressure, flow, load control, etc.), multiple variations are available to help you optimize your control circuit, from individual valves to complete integrated packages. Their expansive product line allows you to develop the best control solution for your hydraulic application.

Sun Hydraulics offers a variety of 2-, 3- and 4-port shuttle cartridges. All shuttle cartridges operate at pressures up to 5000 psi (350 bar).

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.
