The Sun Hydraulics DMDALRN4E24V (DMDALRN4E24V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The DMDALRN4E24V operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and rapid response times, typically around 50 ms. The valve exhibits minimal leakage at high pressures, with maximum leakage specified at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). It supports a switching frequency of up to 15000 cycles per hour, ensuring reliable performance under frequent operation conditions. The valve's construction incorporates Sun's floating style design which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes to the overall durability and reliability of the valve in complex installations. The manual override mechanism requires minimal force (5 lbs at 1000 psi for Port 1), facilitating easy manual operation when necessary. Additionally, the DMDALRN4E24V is compatible with EPDM seals for use with phosphate ester fluids, although these seals must not be exposed to petroleum-based fluids as they can cause damage. The interchangeable coils are another highlight, compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube assembly. This valve's modular design and compatibility features make it an excellent choice for engineers looking to achieve precise control in hydraulic systems while maintaining high performance and reliability across various operational 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.
