The Sun Hydraulics DNCALJV (DNCALJV) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation. This balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The valve's construction allows for port 3 to be used as the inlet and port 1 as the tank, supporting reverse flow though not recommended for optimal performance. Rated for up to 5000 psi (350 bar) service, the solenoid tube assembly of this model is fatigue rated, ensuring durability and reliability under demanding conditions. The DNCALJV operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they will cause damage. The wet armature design of the DNCALJV means that the working fluid surrounds the armature which is susceptible to heat during prolonged coil energization. This can lead to breakdowns in certain fluids like water-glycol mixtures which can form varnishes affecting cartridge function. A wide range of coil termination and voltage options are available for this model, including configurations with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include an IP69K rating option for coil connectors, weatherized coils and kits for enhanced environmental protection, and a unique magnetic design that provides high efficiency and reliable valve shifting. The DNCALJV also benefits from Sun\u2019s floating style construction which reduces risks of internal parts binding due to installation errors or cavity/cartridge machining variations. With a flow capacity of 8 gpm (30 L/min) and quick response times typically around 50 ms, this model is well-suited for applications requiring precise control over fluid handling with minimal leakage and high switching frequency capabilities.

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.
