The Sun Hydraulics DNCALBV (DNCALBV) is a high-performance, solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This model is particularly noted for its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature in maintaining efficiency in pilot control circuits. The DNCALBV operates effectively with a valve capacity based on port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under certain conditions. Constructed to handle demanding applications, this valve boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. It requires no minimum hydraulic pressure for operation, making it versatile across various hydraulic systems. The DNCALBV features EPDM seals configured specifically for phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model incorporates a wet armature design where the working fluid envelops the armature. While this design aids in efficient operation, prolonged coil energization can lead to fluid degradation at elevated temperatures. Users benefit from a wide selection of coil termination and voltage options available with or without surge protection, enhancing customization based on specific application needs. The solenoid of the DNCALBV is engineered for high efficiency with an exceptional magnetic design that delivers potent spool actuating force per watt expended. This ensures reliable valve shifting even under strenuous conditions. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For installation flexibility and durability, Sun Hydraulics incorporates floating style construction in this model to minimize internal part binding due to excessive installation torque or variations in cavity/cartridge machining. With these advanced features and capabilities, the DNCALBV stands out as a superior choice for efficient directional control in hydraulic systems.

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.
