The Sun Hydraulics DMDAMNV824 (DMDAMNV824) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures reliable operation with its fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar). It features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDAMNV824 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. Optional manual overrides (D, L, T controls) incorporate a detent mechanism designed primarily for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. The valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Engineered with a wet armature design, the DMDAMNV824 allows the working fluid to surround the armature which helps in heat dissipation but requires consideration of fluid type due to potential breakdowns at high temperatures. This model also supports interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal part binding due to installation variances. With a maximum flow capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, this valve ensures efficient operation across various applications. Its robust design includes features like a maximum operating pressure of 5000 psi (350 bar), switching frequency up to 15,000 cycles/hr, and minimal manual override force requirements. The compact dimensions and interchangeability of components make the DMDAMNV824 an excellent choice for systems requiring reliable and precise fluid 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.
