The Sun Hydraulics DMDADBN224N (DMDADBN224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design which is ideal for applications requiring precise control. The valve operates without the need for a minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. It is particularly effective when used as pilot controls due to its closed transition between positions B and R, which ensures faster and more consistent response times. This model is equipped with EPDM seals suitable for phosphate ester fluids, though it should not be exposed to petroleum-based substances which could degrade the seals. The DMDADBN224N uses a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat from an energized coil. This factor is crucial in applications using water-glycol mixtures as they can degrade under high temperatures. The valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its robust construction includes Sun\u2019s floating style construction which minimizes internal part binding due to installation inconsistencies or cavity/cartridge machining variations. Additionally, the solenoid coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube for added flexibility. Designed for durability, the manual override mechanism has an expected mechanical life of approximately 7,000 cycles. This model also incorporates features like a typical response time of 50 ms and allows switching frequencies up to 15,000 cycles per hour. With these specifications, the Sun Hydraulics DMDADBN224N valve offers reliable performance tailored for demanding hydraulic control applications.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
