The Sun Hydraulics DMDALNV724 (DMDALNV724) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and precise control in hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), it is suitable for a wide range of applications requiring reliable switching and directional control of fluid flow. The DMDALNV724 features a unique closed transition between spool positions B and R, enhancing performance by ensuring faster and more consistent response times during operation. This makes it particularly effective when used as pilot controls where capacity is less critical but speed and consistency are paramount. The valve's manual override options include detent mechanisms designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Equipped with EPDM seals, the cartridge is ideal for systems using phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design allows the working fluid to surround the armature which helps in heat management but requires consideration regarding the type of fluid used due to potential breakdowns at high temperatures. This model\u2019s construction incorporates Sun\u2019s floating style to minimize internal part binding caused by installation torque or cavity/cartridge machining variations. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube, providing flexibility in application and maintenance. With its robust design, versatile configurations, and reliable performance under high pressures, the Sun Hydraulics DMDALNV724 valve is an excellent choice for advanced hydraulic control in demanding environments.

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.
