The Sun Hydraulics DNCALCV814 (DNCALCV814) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions to minimize oil loss during shifting, which is crucial for maintaining the integrity of pilot control circuits. The valve boasts a capacity based on port 3 as the inlet and port 1 as the tank, with reverse flow possible but not recommended due to potential performance limitations. The DNCALCV814 is fatigue rated for service up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic setups. Notably, this model incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Featuring a wet armature design, the DNCALCV814 allows the working fluid to surround the armature, which could be significant if the coil remains energized over extended periods. This design consideration is essential when using certain fluids that may degrade under prolonged exposure to heat. Additionally, the valve offers a variety of coil termination and voltage options and benefits from Sun Hydraulics' unique magnetic design that enhances solenoid efficiency and reliability in valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Various connector options provide up to IP69K ratings for enhanced durability against environmental conditions. This model also features Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or machining variations in cavity/cartridge setups. With its robust construction and versatile design features, the DNCALCV814 is equipped to deliver reliable performance and precise control in sophisticated 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.
