The Sun Hydraulics DNCALAV748 (DNCALAV748) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to ensure minimal oil loss during position transitions due to its closed transition feature, which is especially beneficial in pilot control circuits. The valve's configuration allows for port 3 to be used as the inlet and port 1 as the tank return, with a capacity of up to 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar. The DNCALAV748 features a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi/350 bar. It operates without requiring a minimum hydraulic pressure, offering versatility in various hydraulic systems. The valve is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods, as it can lead to breakdowns in certain fluids like water-glycol mixtures at high temperatures. To accommodate diverse application needs, Sun Hydraulics offers a wide range of coil termination and voltage options for this model, including options with surge protection. Moreover, the DNCALAV748 benefits from Sun Hydraulics' floating style construction which helps prevent internal parts binding that might occur due to variations in installation torque or cavity/cartridge machining discrepancies. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features such as weatherized coils and kits enhance environmental protection further, ensuring robust performance across various operating conditions.

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.
