The Sun Hydraulics DNCATBV828 (DNCATBV828) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is engineered with a closed transition between positions to significantly reduce oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance degradation. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar), allowing for robust operation without the need for minimum hydraulic pressure. The DNCATBV828 utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids and greases. Its wet armature design allows the working fluid to absorb heat from the coil, which can be a consideration in applications where the coil remains energized for extended periods. This factor should be considered especially when using fluids like water-glycol mixtures that may degrade over time under heat exposure. This model offers various coil termination and voltage options, including those with surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted bidirectionally on the tube. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. Additional specifications include a capacity of 8 gpm (30 L/min), a typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and a switching frequency of up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi and has a stroke length of .10 inches (2.5 mm).

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.
