The Sun Hydraulics DMDATPV228 (DMDATPV228) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed to perform reliably with a maximum operating pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly for demanding applications. It is particularly suitable for use as pilot controls due to its closed transition between spool positions, which ensures faster and more consistent response times without the need for minimum hydraulic pressure. The DMDATPV228 valve incorporates advanced design features including interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installation options. The wet armature design of the valve means the working fluid surrounds the armature, which is crucial in applications where the coil may be energized for extended periods. This model also benefits from Sun\u2019s floating style construction that minimizes internal part binding caused by excessive installation torque or machining variations. With a flow capacity of 12 gpm (45 L/min) and typical response times of 50 ms, this valve ensures efficient operation in hydraulic circuits. It supports switching frequencies up to 15000 cycles/hr and can handle manual override with minimal force requirements. The DMDATPV228 is also equipped with EPDM seals suitable for systems using phosphate ester fluids, providing resilience against certain chemical exposures. This model\u2019s robust construction and high performance specifications make it an excellent choice for sophisticated hydraulic control applications requiring high-speed operation and reliability.

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.
