The Sun Hydraulics DMDADNV924N (DMDADNV924N) is a solenoid-operated 3-way, 2-position cartridge valve that stands out for its direct-acting, balanced spool directional control capabilities. This model is specifically designed to operate without minimum hydraulic pressure, enhancing its utility in various applications. It features a fatigue-rated solenoid tube assembly for services up to 5000 psi or 350 bar, ensuring reliability under high-pressure conditions. The valve's performance is characterized by closed transitions between Spools B and R, which although limits capacity, significantly boosts performance by providing faster and more consistent response times, particularly suitable for pilot controls. The manual override in models with D or L control uses a detent mechanism intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. It is important to note that cartridges configured with EPDM seals are tailored for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage the seals. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature\u2014this aspect needs consideration regarding fluid choice as some can degrade under prolonged heat exposure. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The DMDADNV924N supports up to 12 gpm/45 L/min capacity and incorporates quick response times typically around 50 ms. With these advanced features and robust construction, the Sun Hydraulics DMDADNV924N valve is an optimal choice for sophisticated 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.
