The Sun Hydraulics DMDALRV224N (DMDALRV224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to be fatigue rated for high-pressure scenarios up to 5000 psi (350 bar), making it suitable for demanding operational conditions. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDALRV224N operates without requiring a minimum hydraulic pressure, offering versatility in various system configurations. It includes manual override options with a detent mechanism designed for temporary actuation; however, these are intended mainly for short-term use with a mechanical life expectancy of around 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires careful consideration of fluid type to avoid breakdown and varnish formation. This model is compatible with EPDM seals specifically for systems using phosphate ester fluids; however, it should not be used with petroleum-based fluids as they can damage the seals. Additionally, the interchangeable coils from Sun Series 1 solenoid products add to its flexibility and ease of maintenance. The construction incorporates Sun's floating style design which minimizes internal parts binding due to potential installation torque or machining variations. With specifications including a maximum flow capacity of 12 gpm (45 L/min) and typical response time of 50 ms, along with robust switching capabilities up to 15,000 cycles/hr, the DMDALRV224N is an effective solution for high-frequency switching applications requiring precision and reliability in hydraulic control systems.

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.
