The Sun Hydraulics DNCALTN4E24V (DNCALTN4E24V) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This directional valve is engineered with a closed transition between positions, which significantly reduces oil loss during shifting\u2014a crucial feature for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it is not recommended due to potential performance degradation. It operates efficiently at a maximum pressure of 5000 psi (350 bar) and does not require minimum hydraulic pressure for activation. Designed with fatigue-rated solenoid tube assembly, this valve supports high-efficiency solenoid operation yielding strong spool actuating force per watt expended. The wet armature design allows the working fluid to cool the coil but requires caution with fluid types like water-glycol mixtures that may degrade at elevated temperatures. The DNCALTN4E24V offers versatility in coil termination and voltage options, including surge protection capabilities. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It can handle capacities up to 8 gpm (30 L/min) and has a typical response time of 50 ms. With a switching frequency of up to 15,000 cycles per hour and manual override features requiring minimal force, it ensures reliable performance under demanding conditions. The interchangeable coils are compatible with other Sun Series 1 solenoid products and offer IP69K-rated connector options for enhanced environmental protection. The DNCALTN4E24V weighs approximately .60 lb (0.30 kg) and uses Viton seals suitable for systems utilizing phosphate ester fluids while avoiding petroleum-based substances to prevent seal damage.

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.
