The Sun Hydraulics DNCALZN848 (DNCALZN848) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a closed transition between positions to minimize oil loss during shifting, making it particularly suitable for pilot control circuits. It is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance issues. The valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), and it operates without requiring minimum hydraulic pressure. Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. The valve utilizes a wet armature design, exposing the fluid to coil-generated heat, which can be critical when using water-glycol mixtures that may degrade over time at elevated temperatures. The DNCALZN848 offers multiple coil termination and voltage options, including those with surge protection, ensuring flexibility in various applications. Its high-efficiency solenoid provides significant spool actuating force per watt consumed, resulting in dependable valve transitions. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Connector options support ratings up to IP69K for enhanced environmental resistance, with additional weatherized coils available for comprehensive protection. This model incorporates Sun's floating style construction to reduce internal component binding risks due to excessive installation torque or machining variances in cavity/cartridge interfaces. The DNCALZN848 fits within cavity T-31A of Series 1 valves and has an 8 gpm (30 L/min) capacity at a maximum operating pressure of 5000 psi (350 bar). It features a typical response time of 50 ms and supports a switching frequency of up to 15,000 cycles/hour.

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.
