The Sun Hydraulics DNCALCN924 (DNCALCN924) is a high-performance, solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting operation. This balanced spool directional valve ensures closed transitions between positions, significantly minimizing oil loss during shifting, which is especially beneficial in pilot control circuits. With a design that does not require a minimum hydraulic pressure for operation, this valve features a unique solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it robust for demanding applications. The DNCALCN924 valve is engineered with a wet armature design; the working fluid envelops the armature, potentially affecting fluid characteristics if exposed to heat over extended periods. It supports various coil termination and voltage options, including configurations with surge protection. The coils used are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. This model also incorporates Sun's floating style construction which helps reduce internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve offers impressive durability and reliability with features like IP69K-rated coil connector options and additional weatherized coils for enhanced environmental protection. Key specifications include an operational capacity of 8 gpm (30 L/min) at a maximum pressure of 5000 psi (350 bar). It has a swift response time of approximately 50 ms and allows for a maximum switching frequency of 15000 cycles per hour. The manual override features require minimal force, highlighting its ease of use in manual operations. This model's compact and efficient design makes it suitable for various hydraulic applications requiring precise control and reliability.

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.
