The Sun Hydraulics DNCALLN624N (DNCALLN624N) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional design. This valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014an essential attribute for pilot control circuits. Designed to operate with port 3 as the inlet and port 1 as the tank, reverse flow is possible but not recommended for optimal performance. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve requires no minimum hydraulic pressure for operation and utilizes EPDM seals suitable for phosphate ester fluid systems, though these seals are incompatible with petroleum-based fluids. The wet armature design allows the working fluid to cool the armature but may affect fluids like water-glycol mixtures over prolonged coil energization due to heat exposure. The DNCALLN624N offers various coil termination and voltage options, including surge protection features. Its high-efficiency solenoid provides robust spool actuating force per watt, ensuring reliable valve shifts. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Available coil connector options offer protection ratings up to IP69K for enhanced environmental resilience. Key specifications include an 8 gpm (30 L/min) capacity and a maximum operating pressure of 5000 psi (350 bar). The typical response time is around 50 ms, with a maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). This model supports a switching frequency of up to 15,000 cycles per hour and features a manual override stroke of .10 inches (2.5 mm). The valve's compact design includes a .75-inch solenoid tube diameter and requires an installation torque between 30-35 lbf ft (41-47 Nm).

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.
