The Sun Hydraulics DNCALTV612N (DNCALTV612N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is particularly suitable for applications where minimizing oil loss during position shifts is critical, such as in pilot control circuits. It features a closed transition between positions to achieve this reduction in oil loss. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance degradation. Engineered for high-pressure environments, the solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar). The design requires no minimum hydraulic pressure for operation, making it versatile across various system requirements. Notably, cartridges configured with EPDM seals should be used exclusively with phosphate ester fluids to prevent damage from petroleum-based substances. The wet armature design allows working fluid to surround the armature, which could affect fluid stability if the coil remains energized for extended periods. This feature should be considered when using fluids prone to breakdown at elevated temperatures. The solenoid's magnetic design ensures high efficiency and reliable valve shifting by providing significant spool actuating force per watt expended. This model offers various coil termination and voltage options, including configurations with surge protection and weatherized coils that can achieve ratings up to IP69K for enhanced environmental protection. Additionally, its floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and a rapid response time of approximately 50 ms, this valve supports switching frequencies up to 15,000 cycles per hour. The manual override requires minimal force and stroke for operation. Seal kits are available in Viton material for both cartridge and coil components.

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.
