The Sun Hydraulics DMDAMRN224 (DMDAMRN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The transition between the spool positions B and R is closed, which enhances performance limits while reducing capacity\u2014an ideal setup when used as pilot controls for faster and more consistent response times without the dependency on hydraulic pressure. Equipped with EPDM seals, the DMDAMRN224 is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided as it could damage the seals. The valve's wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. The construction incorporates Sun\u2019s floating style design that minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This valve offers a maximum flow capacity of 12 gpm (45 L/min) and features rapid response times typically around 50 ms. Manual override options are available, designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The DMDAMRN224 maintains operational reliability with switching frequencies up to 15,000 cycles per hour and exhibits minimal leakage even at high pressures. This model is an essential component for systems requiring precise control and reliability in hydraulic operations, providing both durability and performance efficiency in a compact design.

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.
