The Sun Hydraulics DNCALSV524 (DNCALSV524) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity 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. It operates efficiently at a maximum pressure of 5000 psi (350 bar) without requiring minimum hydraulic pressure for activation. The DNCALSV524 employs a wet armature design that allows the working fluid to absorb heat generated by the coil, a factor to consider for long-term coil energization\u2014especially with fluids like water-glycol mixtures that may degrade at high temperatures. The solenoid's magnetic design enhances efficiency, delivering high actuating force per Watt and ensuring reliable valve operation. A range of coil termination and voltage options are available, some offering surge protection and environmental ratings up to IP69K. Installation flexibility is provided through interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either orientation on the tube. The floating style construction minimizes risks of internal binding from installation torque or machining variations. With a capacity of 8 gpm (30 L/min), response time around 50 ms, and switching frequency up to 15,000 cycles per hour, this model offers robust performance for demanding applications. The valve requires manual override force of approximately 5 lbs/1000 psi at Port 1 and features a manual override stroke of .10 inches (2.5 mm). Seal kits are available in Viton material for both cartridge and coil components to ensure compatibility with various fluid types.

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.
