The Sun Hydraulics DMDALPN724N (DMDALPN724N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is capable of operating at a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a robust design with interchangeable coils that are compatible with other Sun Series 1 solenoid products, allowing for flexible installation options. The DMDALPN724N valve incorporates a wet armature design, where the working fluid surrounds the armature. This setup is crucial for certain applications but requires consideration of the fluid type due to potential breakdowns at high temperatures. Specifically, the valve uses EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For manual operation, the valve includes a detent mechanism in its manual override which is designed for temporary actuation. The mechanical life expectancy of this control assembly is around 7,000 cycles. Additionally, it features Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a typical response time of 50 ms and a maximum leakage rate at 110 SUS (24 cSt) under 3000 psi (210 bar) pressure conditions. The manual override requires an actuation force of about 5 lbs at 1000 psi for Port 1. The durability and operational reliability make this valve an excellent choice for applications requiring precise control with high frequency switching up to 15,000 cycles per hour.

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.
