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' pilot-to-open check cartridges are non-modulating, on-off devices used for holding a load or actuator in position. Sun pilot-to-open check cartridges can be directly integrated into your actuator or applied using manifolds with many mounting options.

• Offer protection against hose breaks
• Positively lock pressurized loads
• Are available in non-vented (3-port) and vented (3- and 4-port) versions
• Are physically interchangeable with counterbalance cartridges (same number of ports, same cavities, same flow path for a given frame size).
