The Sun Hydraulics DMDAMRVHN24AB (DMDAMRVHN24AB) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed for high-pressure applications up to 5000 psi (350 bar) and is fatigue rated for rigorous use. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDAMRVHN24AB operates without the need for minimum hydraulic pressure, making it versatile for various hydraulic circuits. It includes manual override options with detent mechanisms designed for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design ensures that the working fluid surrounds the armature which may affect fluid integrity under prolonged energized conditions. However, it uses EPDM seals specifically suited for phosphate ester fluids but should avoid contact with petroleum-based substances to prevent seal damage. Interchangeability of coils with other Sun Series 1 solenoid products allows flexibility in maintenance and upgrades, ensuring operational continuity and ease of integration into existing systems. Additionally, the valve incorporates Sun's floating style construction which minimizes internal parts binding from installation stresses or cavity-cartridge machining variations. This model supports up to 12 gpm (45 L/min) flow capacity and offers swift response times typically around 50 ms. It is engineered to handle switching frequencies up to 15,000 cycles per hour while maintaining minimal leakage at high pressures. The compact design includes a .75 inch (19 mm) solenoid tube diameter and weighs just .60 lb (0.30 kg), making it an efficient choice for space-conscious applications requiring reliable hydraulic control.

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.
