The Sun Hydraulics DNCALLV212 (DNCALLV212) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is particularly beneficial in pilot control circuits due to its closed transition between positions, which significantly reduces oil loss during shifting. Optimized for use with port 3 as the inlet and port 1 as the tank, reverse flow is possible but not recommended for maintaining performance standards. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust service life without needing minimum hydraulic pressure for operation. It incorporates EPDM seals suitable for phosphate ester fluid systems while being incompatible with petroleum-based fluids. The valve employs a wet armature design that exposes the working fluid to coil-generated heat; caution is advised if using fluids like water-glycol mixtures that may degrade over time at elevated temperatures. A variety of coil termination and voltage options are available, including configurations with surge protection and IP69K-rated connectors for enhanced environmental resilience. The high-efficiency magnetic solenoid design provides reliable valve shifting by maximizing spool actuating force per watt of power used. Coils are interchangeable within Sun's Series 1 solenoids and can be mounted bidirectionally on the tube. This valve supports a cavity T-31A configuration with an 8 gpm (30 L/min) capacity and features a rapid response time typically around 50 ms. It allows up to 15,000 switching cycles per hour and maintains low leakage at specified conditions. For manual operation, it requires an override force of approximately 5 lbs/1000 psi (33 N/100 bar) with a stroke length of .10 inches (2.5 mm). The DNCALLV212 model weighs .60 lb (.30 kg) and includes Viton seal kits available separately for maintenance needs.

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.
