The Sun Hydraulics DNCALLN828 (DNCALLN828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is particularly valuable in pilot control circuits due to its closed transition between positions, which significantly reduces oil loss during shifting. With a valve capacity focused on port 3 as the inlet and port 1 as the tank, it is important to note that while reverse flow is possible, it is not recommended due to potential performance inconsistencies. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DNCALLN828 operates without the need for minimum hydraulic pressure thanks to its direct-actuated design. It features EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. A wet armature design allows the working fluid to surround the armature, which can be advantageous but requires consideration of fluid breakdown under heat generated by prolonged coil energization. This model provides various coil termination and voltage options with or without surge protection and boasts a unique magnetic design that enhances efficiency by maximizing spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Additionally, coil connector options are available with ratings up to IP69K for enhanced environmental protection. Built with Sun's floating style construction, this valve minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge configurations. It fits into cavity T31A and offers an impressive capacity of 8 gpm (30 L/min) with a typical response time of 50 ms and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar).

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.
