The Sun Hydraulics DNCALLV624N (DNCALLV624N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014an essential attribute for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to performance considerations. It operates efficiently at pressures up to 5000 psi (350 bar) without requiring minimum hydraulic pressure for activation. The DNCALLV624N employs a wet armature design that allows the working fluid to surround the armature, which may influence performance if the coil remains energized for extended periods. This feature makes it crucial to consider fluid compatibility, especially with water-glycol mixtures that could degrade under heat exposure. The valve supports various coil termination and voltage options and includes surge protection capabilities. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Constructed with Sun's floating style design, this model minimizes internal part binding risks due to excessive installation torque or machining variations. It offers a maximum flow capacity of 8 gpm (30 L/min) and boasts a rapid response time of approximately 50 milliseconds. The DNCALLV624N also supports high switching frequencies up to 15,000 cycles per hour and maintains low leakage rates under specified conditions. With its robust construction and adaptable design features, this valve is well-suited for demanding hydraulic applications requiring reliable performance and efficient fluid management.

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.
