The Sun Hydraulics DNCALWV914N (DNCALWV914N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical attribute for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it may not meet performance expectations and is not recommended. Engineered for durability, the solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar). This valve operates without requiring minimum hydraulic pressure due to its direct actuation mechanism. Cartridges equipped with EPDM seals are suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. The wet armature design immerses the armature in working fluid, which can absorb heat from the coil\u2014important when considering fluids like water-glycol mixtures that may degrade at elevated temperatures. Various coil termination and voltage options are available, including configurations with surge protection. The solenoid's efficient magnetic design ensures high spool actuating force per watt consumed, enhancing reliability in valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted bi-directionally on the tube. Coil connector options provide protection ratings up to IP69K, with additional weatherized coils and kits available for enhanced environmental resilience. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Key specifications include a cavity size of T31A, series designation of 1, capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at specified viscosity of 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar).

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.
