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.

This FLeX Series solenoid-operated 2-way, 2-position cartridge is a direct-acting directional poppet valve. Available in either normally open or normally closed configurations, these valves feature a pressure-balanced design, low leakage, and allow flow or blocking in both directions.

This cartridge can be installed directly into a cavity in the end of many of Sun's pilot operated and ventable valves to provide integrated pilot control.

• Cartridge can be installed directly into a cavity in some Sun pilot operated and ventable cartridges to provide electrically operated pilot control functions. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function.
• Suitable for load-holding applications when configured as Normally Closed. In the event of power failure, the valve will close.
• 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.
• Designed and tested to 10-million operational cycles at full-rated pressure.
• Exceeds new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
• Higher flow rates than competing valves of similar size.
• Designed using CFD simulation for optimized geometries.
• All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.
• Normally Closed configuration can be used with any of the 740 Series coils, which include low-power, high-power, and 747 Series explosion-proof coils. Normally Open configuration can be used with the high-power and explosion proof coils only.
