The Sun Hydraulics DNCAMLV812N (DNCAMLV812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is characterized by its closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical feature for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it does not guarantee the same performance and is not recommended. It features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), enabling robust service in demanding applications. The direct actuation of this valve eliminates the need for minimum hydraulic pressure to operate. The DNCAMLV812N utilizes a wet armature design where working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration should be noted when using fluids such as water-glycol mixtures that can degrade over time at elevated temperatures. A variety of coil terminations and voltage options are available, some with surge protection, enhancing versatility in different setups. The high-efficiency solenoid design ensures reliable valve shifting with significant spool actuating force per watt expended. Interchangeable coils with other Sun Series 1 solenoid products add to its adaptability, allowing mounting in either direction on the tube. Coil connector options offer ratings up to IP69K for enhanced environmental protection. The floating style construction minimizes potential binding of internal parts due to excessive installation torque or machining variations in cavity-cartridge interfaces. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve meets rigorous demands while maintaining minimal leakage and rapid response times ideal for high-frequency switching applications up to 15,000 cycles per hour.

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.
