The Sun Hydraulics DNCAMBV928 (DNCAMBV928) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct acting and balanced spool directional control. This valve is engineered with a closed transition between positions, significantly reducing oil loss during shifting\u2014a critical feature for pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, although reverse flow is not recommended due to potential performance issues. The solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust service life. This direct-actuated valve does not require a minimum hydraulic pressure for operation, making it versatile in various applications. The DNCAMBV928 features EPDM seals compatible with phosphate ester fluids but unsuitable for petroleum-based substances. Its wet armature design allows working fluid to cool the armature but requires caution with water-glycol mixtures that may degrade at high temperatures over time. The valve offers various coil termination and voltage options, including surge protection, enhancing its adaptability across different systems. The high efficiency of its unique magnetic solenoid design ensures reliable valve shifting by maximizing actuating force per watt. Sun's floating style construction minimizes the risk of internal part binding due to excessive installation torque or cavity machining variations. It fits into a T-31A cavity and belongs to Series 1 with an 8 gpm (30 L/min) capacity and a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 50 ms, with leakage rates capped at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports up to 15,000 cycles per hour switching frequency and includes manual override features requiring minimal force. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally, providing flexibility in installation configurations.

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.
