The Sun Hydraulics DNCALLN228 (DNCALLN228) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a crucial advantage in pilot control circuits. The valve is optimized with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. With a solenoid tube assembly fatigue rated for service at 5000 psi (350 bar), this valve requires no minimum hydraulic pressure for operation. It employs EPDM seals suitable for phosphate ester fluid systems and should avoid petroleum-based fluids to prevent seal damage. Utilizing a wet armature design, the working fluid surrounds the armature and can be affected by coil-generated heat over time\u2014particularly in water-glycol mixtures that may degrade into varnishes impacting function. The DNCALLN228 offers various coil termination and voltage configurations, with options including surge protection. Its high-efficiency magnetic design delivers substantial spool actuating force per watt, ensuring reliable operation. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector choices provide ratings up to IP69K, with additional weatherized coils available for enhanced environmental protection. This valve incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1, with an operational capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 50 ms, with maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports a switching frequency of up to 15,000 cycles/hr and requires manual override force of around 5 lbs/1000 psi (33 N/100 bar at Port 1).

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.
