The Sun Hydraulics DMDADPV824 (DMDADPV824) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and optimized functionality in demanding applications. It operates with a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features closed transition spools B and R, enhancing its performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDADPV824 incorporates several design enhancements including a fatigue-rated solenoid tube assembly suitable for high-pressure service and a wet armature design that surrounds the armature with working fluid to manage heat during prolonged coil energization. However, this can affect fluid integrity over time, especially with water-glycol mixtures. It also includes interchangeable coils compatible with other Sun Series 1 solenoid products, facilitating flexible installation options. This model employs EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The manual override feature provided by the D or L control is designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Additionally, the floating style construction minimizes internal parts binding caused by installation torque or machining variations of cavity/cartridge. The valve's quick response time (typically 50 ms), low maximum leakage at high pressures (5 in\u00b3/min at 3000 psi), and high switching frequency (15000 cycles/hr) make it an effective solution for various hydraulic control systems requiring precise fluid management under high-pressure 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.
