The Sun Hydraulics DMDADRN4E24V (DMDADRN4E24V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to function optimally within a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a rapid response time of approximately 50 ms, which is crucial for applications requiring quick actuation. The DMDADRN4E24V incorporates advanced design elements such as the Sun floating style construction which significantly reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This valve is particularly noted for its robust manual override feature which includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. An important aspect of this model is its wet armature design where the working fluid surrounds the armature. Although this design aids in efficient operation, it requires careful consideration regarding the type of fluid used; specifically, EPDM seals in this model are suitable only for systems utilizing phosphate ester fluids. The valve's compatibility with other Sun Series 1 solenoid products allows for interchangeable coils that can be mounted in either direction on the tube, enhancing flexibility and ease of use in various hydraulic setups. Furthermore, the valve\u2019s design ensures minimal leakage at high pressures and offers a switching frequency capable of handling up to 15,000 cycles per hour. These features make the DMDADRN4E24V an excellent choice for demanding applications where precision and reliability are paramount.

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.
