The Sun Hydraulics DMDAMBV824 (DMDAMBV824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve operates efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). It features a quick response time of approximately 50 ms, ensuring timely operation in various applications. Key to its design is the closed transition between Spools B and R, which enhances performance by ensuring consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve's robust construction includes a fatigue-rated solenoid tube assembly for long-term durability even under high-pressure conditions. The DMDAMBV824 incorporates several user-centric features such as interchangeable coils compatible with other Sun Series 1 solenoid products, allowing for flexible usage and easy maintenance. Its manual override mechanism is designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, the valve utilizes EPDM seals suitable for systems using phosphate ester fluids, though these seals must be shielded from exposure to petroleum-based substances which could cause damage. This model also benefits from Sun\u2019s floating style construction which minimizes internal binding due to installation torque or machining variations in the cavity/cartridge setup. The practical design considerations extend to easy installation with specific torque requirements (30 \u2013 35 lbf ft) and manageable weight (.60 lb), making the DMDAMBV824 both reliable and user-friendly in demanding hydraulic applications.

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.
