The Sun Hydraulics DNCAMLN72419 (DNCAMLN72419) 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 to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. This valve operates 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. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), and the valve functions without requiring a minimum hydraulic pressure. Cartridges equipped with EPDM seals are intended for use with phosphate ester fluids and are not compatible with petroleum-based fluids. The wet armature design exposes the armature to working fluid and heat from the coil, which could affect certain fluids like water-glycol mixtures over time. The DNCAMLN72419 offers various coil termination and voltage options, some with surge protection. Its magnetic design ensures high efficiency by maximizing spool actuating force per Watt, enhancing reliability in valve shifting. Coils are interchangeable within Sun Series 1 solenoids and can be installed in either direction on the tube. Coil connectors provide ratings up to IP69K for environmental protection, with additional weatherized coils available. The floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. Key specifications include a cavity size of T31A, series 1 capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, maximum leakage at 10 in\u00b3/min (3000 psi/160 cc/min/210 bar), switching frequency of up to 15,000 cycles/hr, manual override force requirement of 5 lbs/1000 psi (33 N/100 bar) at Port 1, manual override stroke of .10 in (2.5 mm), solenoid tube diameter of .75 in (19 mm), valve hex size of .78 in (22.2 mm), installation torque range of 30-35 lbf ft (41-47 Nm), model weight of .60 lb (.30 kg), and Viton seal kits available for both cartridge and coil components.

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.
