The Sun Hydraulics DNCALBV4E12V (DNCALBV4E12V) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a crucial feature for maintaining efficiency in pilot control circuits. It operates with a valve capacity based on port 3 as the inlet and port 1 as the tank, supporting reverse flow under specific conditions though not recommended due to potential performance variations. The DNCALBV4E12V is engineered to handle maximum pressures up to 5000 psi (350 bar) and is fatigue rated for demanding applications. It does not require minimum hydraulic pressure for operation, making it versatile for various hydraulic systems. The valve incorporates EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. Featuring a wet armature design, the DNCALBV4E12V's working fluid surrounds the armature which could be subject to heat from the coil if energized for extended periods. This aspect needs consideration especially with fluids like water-glycol mixtures that might degrade under prolonged heat exposure. For customization and adaptability in different environments, this model offers a range of coil termination and voltage options, including versions with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. Connector options provide protection ratings up to IP69K with additional weatherized coils available for enhanced environmental resistance. This model also benefits from Sun\u2019s floating style construction which helps prevent internal part binding due to installation variances or excessive torque during setup. With its robust design and efficient magnetic configuration that maximizes actuating force per watt expended, the DNCALBV4E12V ensures reliable valve shifting and high-performance operation across various applications.

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.
