The Sun Hydraulics DMDAMAV924N (DMDAMAV924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve ensures reliable control in various hydraulic systems. It is uniquely engineered to operate without minimum hydraulic pressure, making it versatile across different operational scenarios. The valve features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), suitable for high-pressure applications. The design includes closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control setups where capacity is less critical. This model also incorporates a wet armature design, allowing the working fluid to surround the armature which helps in heat management during prolonged coil energization. For durability and reliability, the manual override mechanism included in models with D or L control is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the valve uses EPDM seals specifically for systems with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The cartridge's construction benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It supports a maximum flow capacity of 12 gpm (45 L/min) and features interchangeable coils with other Sun Series 1 solenoid products which can be mounted in either direction on the tube. This model also offers an impressive switching frequency of up to 15,000 cycles per hour and has been crafted with attention to detail including manual override specifications like force requirements and stroke limits.

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.
