The Sun Hydraulics DNCALCV2E12V (DNCALCV2E12V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool and closed transition between positions. This design significantly reduces oil loss during shifts, which is crucial in pilot control circuits. The valve operates efficiently with no minimum hydraulic pressure required and features a unique solenoid magnetic design that delivers high spool actuating force per watt expended, ensuring reliable valve shifting. This model is fatigue rated for service up to 5000 psi (350 bar) and incorporates a wet armature design where the working fluid surrounds the armature. This could be a consideration if the coil remains energized for extended periods as some fluids may degrade under prolonged exposure to heat. The DNCALCV2E12V supports reverse flow, although optimal performance in this mode isn't guaranteed. It has an array of coil termination and voltage options available, including configurations with surge protection. Particularly suited for systems using phosphate ester fluids, cartridges with EPDM seals should not be exposed to petroleum-based substances which can damage these seals. The valve\u2019s construction uses Sun\u2019s floating style to minimize internal binding due to installation variances or machining errors. It offers an IP69K rating option for coil connectors which enhances environmental protection along with additional weatherized coils and kits. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity at 8 gpm (30 L/min), typical response time of 50 ms, and manual override features that require minimal force. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can handle up to 15,000 switching cycles per hour.

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.
