The Sun Hydraulics DNCALZN299 (DNCALZN299) is a solenoid-operated, 4-way, 2-position cartridge valve designed as a direct-acting, balanced spool directional valve. It features a closed transition between positions to minimize oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve is configured with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance issues. Designed for high-pressure applications, the solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar). This direct-actuated valve requires no minimum hydraulic pressure for operation and incorporates EPDM seals suitable for phosphate ester fluid systems; however, exposure to petroleum-based fluids can damage these seals. The wet armature design allows working fluid to surround the armature, which could affect performance if the coil is energized for extended periods, especially with certain fluids like water-glycol mixtures that may degrade at high temperatures. The DNCALZN299 offers various coil termination and voltage options with or without surge protection. Its unique magnetic design ensures high efficiency by delivering significant spool actuating force per watt used. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The valve utilizes Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. This model fits into a T-31A cavity and operates with a capacity of 8 gpm (30 L/min) under maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 50 ms and can handle a switching frequency of up to 15,000 cycles per hour. The manual override requires minimal force and stroke for operation, while installation torque ranges 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.
