The Sun Hydraulics DNCALLV228 (DNCALLV228) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. It is engineered with a closed transition between positions to minimize oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is possible but not recommended due to potential performance issues. This component operates effectively at a maximum pressure of 5000 psi (350 bar) and does not require minimum hydraulic pressure for activation due to its direct actuation. The DNCALLV228 utilizes a wet armature design that allows the working fluid to surround the armature, which can be affected by heat from the coil if energized for extended periods. This design consideration is crucial when using fluids prone to breakdown at high temperatures, such as water-glycol mixtures. The valve offers multiple coil termination and voltage options, with some configurations providing surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. A notable feature of this valve is its high-efficiency solenoid magnetic design, which provides substantial spool actuating force per watt expended. This leads to reliable valve shifting even under demanding conditions. The DNCALLV228 incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge designs. Additional specifications include a cavity size of T-31A, series 1 designation, an 8 gpm (30 L/min) capacity, typical response time of 50 ms, and a maximum switching frequency of 15,000 cycles per hour. The valve's manual override requires a force of approximately 5 lbs/1000 psi (33 N/100 bar at Port 1), with an override stroke of .10 inches (2.5 mm).

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.
