The Sun Hydraulics DMDAMRVHN24AA (DMDAMRVHN24AA) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. Featuring a direct-acting, balanced spool directional valve mechanism, it ensures reliable operation with no minimum hydraulic pressure required for activation. This model is particularly notable for its fatigue-rated solenoid tube assembly, capable of handling up to 5000 psi (350 bar), making it suitable for rigorous applications. The valve exhibits closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for use as pilot controls where capacity is less critical. It incorporates a wet armature design; the working fluid surrounds the armature which can be a consideration if the coil remains energized over extended periods due to potential heat-related fluid degradation. This model also features interchangeable coils with other Sun Series 1 solenoid products and can be installed in either direction on the tube. The design includes Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve also supports a switching frequency of up to 15000 cycles per hour and has manual override capabilities with specific force and stroke requirements. Additionally, this valve is equipped with EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids to prevent seal damage. This product offers robust performance for complex hydraulic systems requiring precise control and rapid response in various operational conditions.

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.
