The Sun Hydraulics DNCALTV712N (DNCALTV712N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient and reliable directional control in hydraulic systems. This direct-acting, balanced spool valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical aspect for pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at a maximum service pressure of 5000 psi (350 bar), ensuring durability under demanding conditions. The valve requires no minimum hydraulic pressure to operate and utilizes a wet armature design that exposes the working fluid to coil-generated heat. This design consideration is essential when using fluids like water-glycol mixtures that may degrade at high temperatures over time. The DNCALTV712N offers various coil termination and voltage options, some with surge protection, and features interchangeable coils compatible with other Sun Series 1 solenoid products. These coils can be mounted in either direction on the tube and offer IP69K-rated connector options for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min), it supports a maximum operating pressure of 5000 psi (350 bar) and typical response time of approximately 50 ms. The valve's switching frequency reaches up to 15000 cycles per hour, while manual override functions require minimal force and stroke distance for operation. The product dimensions include a solenoid tube diameter of .75 inches (19 mm) and an installation torque range of 30-35 lbf-ft (41-47 Nm). Seal kits are available in Viton material for both cartridge and coil applications, ensuring compatibility with specific fluid types such as phosphate ester fluids while avoiding petroleum-based exposures that could damage EPDM seals.

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.
