The Sun Hydraulics DNCAMWV912N (DNCAMWV912N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient fluid control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifts, which is particularly beneficial in pilot control circuits. It 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 valve\u2019s solenoid tube assembly is fatigue rated for service pressures up to 5000 psi (350 bar), ensuring durability and reliability. This model does not require minimum hydraulic pressure for operation and utilizes EPDM seals suitable for phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The wet armature design allows the working fluid to surround the armature, exposing it to coil-generated heat\u2014an important consideration when using water-glycol mixtures that may degrade over time at elevated temperatures. Offering high efficiency through its unique magnetic design, this solenoid provides significant spool actuating force per watt expended. It supports various coil termination and voltage options with or without surge protection, and its coils are interchangeable with other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. Key specifications include a capacity of 8 gpm (30 L/min), response time of approximately 50 ms, maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and a switching frequency of up to 15,000 cycles per hour. The valve features Sun\u2019s floating style construction to prevent internal binding from excessive installation torque or machining variations. With a hex size of .78 inches (22.2 mm) and installation torque between 30-35 lbf ft (41-47 Nm), this cartridge valve offers robust performance in demanding applications.

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.
