The Sun Hydraulics DMDAMNV223 (DMDAMNV223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust industrial applications. Featuring a direct-acting, balanced spool design, this valve ensures reliable operation with no minimum hydraulic pressure required. It is particularly noted for its fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure systems. The DMDAMNV223 model incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times during pilot control operations. This design choice, while limiting flow capacity, enhances the operational speed and reliability essential in critical environments. The valve's manual override features a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model uses EPDM seals specifically suited for systems utilizing phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based products. The wet armature design of the valve means that the working fluid surrounds the armature which can lead to thermal degradation of certain fluid types if the coil remains energized over extended periods. Interchangeability is a key feature with the DMDAMNV223 as its coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction includes Sun\u2019s floating style which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup. With specifications like a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and rapid typical response times around 50 ms, this valve is engineered to meet demanding application requirements efficiently. Its robust design and versatile features make it an ideal choice for systems requiring precise control with high 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.
