The Sun Hydraulics DNCAMBV228 (DNCAMBV228) is a solenoid-operated, 4-way, 2-position cartridge valve designed with a direct-acting, balanced spool mechanism. This valve is particularly valued for its closed transition feature, which minimizes oil loss during position changes\u2014a critical aspect in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is engineered to withstand fatigue at pressures up to 5000 psi (350 bar), ensuring durability under high-stress conditions. Notably, this valve operates without requiring minimum hydraulic pressure and incorporates EPDM seals suitable for phosphate ester fluid systems; however, these seals are vulnerable to petroleum-based fluids. The DNCAMBV228 employs a wet armature design where the working fluid cools the armature, which can affect fluid integrity over prolonged coil energization. It offers versatile coil termination and voltage options, including surge protection configurations. The high efficiency of the solenoid's magnetic design ensures reliable spool actuation with minimal energy consumption. Coils are interchangeable within the Sun Series 1 range and can be mounted in either direction on the tube. This model integrates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It features a cavity size of T31A with an operational capacity of up to 8 gpm (30 L/min) and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports a switching frequency of up to 15,000 cycles per hour and requires minimal manual override force. Additional specifications include a response time of approximately 50 milliseconds and compatibility with Viton seal kits for enhanced performance reliability.

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.
