The Sun Hydraulics DNCALCV812 (DNCALCV812) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition shifting. This design significantly minimizes oil loss during position changes, enhancing efficiency in pilot control circuits. The valve offers a capacity of 8 gpm/30 L/min with maximum operating pressure up to 5000 psi/350 bar and allows for reverse flow, although performance consistency in reverse may not be guaranteed. This model is equipped with EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based substances which could damage the seals. The wet armature design of the solenoid ensures the working fluid surrounds the armature; however, prolonged energization can lead to heat buildup affecting fluid integrity over time. It boasts quick response times typically around 50 ms and maintains low leakage rates at high pressures. The DNCALCV812 provides various coil termination and voltage options including surge protection configurations, compatible across Sun Series 1 solenoid products with interchangeable coils that can be mounted in any direction. Coil connectors are rated up to IP69K for enhanced environmental protection against elements. This model also incorporates Sun\u2019s floating style construction which reduces risks of internal parts binding due to installation torque or machining variations of cavity/cartridge. With its robust magnetic design and efficient solenoid operation, the DNCALCV812 ensures reliable valve actuation and high performance in demanding hydraulic 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.
