The Sun Hydraulics DNCAMSV812 (DNCAMSV812) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool valve features a closed transition between positions, significantly reducing oil loss during shifting\u2014a crucial attribute for pilot control circuits. With a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), this valve ensures reliable performance without the need for minimum hydraulic pressure. It supports a flow capacity of 8 gpm (30 L/min) 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 DNCAMSV812 utilizes a wet armature design where the working fluid cools the coil, which can be significant if the coil is energized for extended periods. This design consideration is particularly important when using fluids like water-glycol mixtures that may degrade at higher temperatures over time. The valve offers various coil termination and voltage options, including configurations with surge protection, ensuring compatibility with diverse system requirements. The unique magnetic design of the solenoid enhances efficiency by delivering high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either direction on the tube. For enhanced environmental protection, coil connector options are available with ratings up to IP69K, along with additional weatherized coils and kits. Incorporating Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge assemblies. The DNCAMSV812 supports a switching frequency of up to 15,000 cycles per hour and features manual override capabilities with specific force and stroke requirements for added operational flexibility.

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.
