The Sun Hydraulics DNCAMBN812N (DNCAMBN812N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is engineered to provide a closed transition between positions, significantly reducing oil loss during shifting\u2014an advantage particularly useful in pilot control circuits. It is designed 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 valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), and it requires no minimum hydraulic pressure for operation. Configured with EPDM seals, this model is suitable for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage the seals. The wet armature design allows the working fluid to surround the armature, which can be affected by heat generated from the coil if energized for extended periods. This characteristic should be considered in systems using water-glycol mixtures, as they may degrade over time at high temperatures. The DNCAMBN812N offers various coil termination and voltage options, some with surge protection capabilities. Its high-efficiency solenoid provides substantial spool actuating force per watt expended, ensuring reliable valve operation. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options are rated up to IP69K for robust environmental protection. The valve also incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or cavity machining variations. With a capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, this cartridge valve supports a maximum operating pressure of 5000 psi (350 bar). It features a manual override force requirement of 5 lbs/1000 psi (33 N/100 bar) at Port 1 and 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.
