The Sun Hydraulics DNCALCN299 (DNCALCN299) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition between positions. This design significantly minimizes oil loss during shifting, which is especially beneficial in pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, though it supports reverse flow under certain conditions. Rated for up to 5000 psi (350 bar) service, the solenoid tube assembly of the DNCALCN299 is fatigue rated, ensuring durability and long-term performance. The valve does not require a minimum hydraulic pressure to operate due to its direct actuation. It is compatible with systems using phosphate ester fluids when configured with EPDM seals but should not be used with petroleum-based fluids which can damage the seals. The DNCALCN299 employs a wet armature design where the working fluid surrounds the armature. This setup needs consideration as prolonged coil energization could lead to fluid breakdown in certain types like water-glycol mixtures. The valve also boasts a variety of coil termination and voltage options, including models with surge protection. Key features include interchangeable coils compatible with other Sun Series 1 solenoid products, multiple coil connector options rated up to IP69K for enhanced environmental protection, and Sun's floating style construction that reduces internal part binding risks. The valve offers reliable performance characteristics such as a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour. Additionally, manual override capabilities are integrated into its design. With an installation torque requirement between 30 \u2013 35 lbf ft (41 \u2013 47 Nm) and weighing only 0.60 lb (0.30 kg), this compact yet robust valve ensures reliable operation and ease of use in various hydraulic applications.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
