The Sun Hydraulics DNCAMWV812 (DNCAMWV812) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical factor in pilot control circuits. It is optimized for use with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly of this valve is fatigue-rated for a service pressure of up to 5000 psi (350 bar), requiring no minimum hydraulic pressure for operation. This model supports systems using phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The DNCAMWV812 employs a wet armature design that allows the working fluid to surround the armature and absorb heat generated by the coil\u2014important to consider as prolonged coil energization can lead to fluid degradation in certain mixtures like water-glycol. The valve boasts high efficiency due to its unique magnetic design, providing substantial spool actuating force per watt expended. It offers versatility with various coil termination and voltage options available, including those with surge protection, interchangeable coils within Sun Series 1 products, and connector options rated up to IP69K for enhanced environmental protection. This model incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and rapid response time of approximately 50 ms, it supports switching frequencies up to 15,000 cycles per hour. The manual override function requires minimal force and features a stroke length of .10 inches (2.5 mm). The valve's compact design includes a .75-inch solenoid tube diameter and requires an installation torque between 30-35 lbf-ft (41-47 Nm).

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.
