The Sun Hydraulics DNCALCV628 (DNCALCV628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve operates effectively with port 3 as the inlet and port 1 as the tank, although it allows reverse flow; the performance in reverse configuration may vary. With a robust design that includes a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), this valve ensures reliable operation under demanding conditions. It does not require any minimum hydraulic pressure to function, making it versatile for various applications. The DNCALCV628 is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model employs a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat from an energized coil. The DNCALCV628 offers multiple coil termination and voltage options and incorporates Sun\u2019s floating style construction which reduces internal part binding due to installation variances. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, various IP69K rated connector options for enhanced environmental protection, and a maximum operating capacity of 8 gpm (30 L/min). With its quick response time of approximately 50 ms and capability of handling up to 15000 switching cycles per hour, this valve is an efficient solution for dynamic hydraulic systems requiring precise control and reliability.

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.
