The Sun Hydraulics DMDAXPV212 (DMDAXPV212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to offer reliable control in hydraulic systems. It features a fatigue rating for 5000 psi (350 bar), making it suitable for high-pressure applications. The unique construction of the valve ensures closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially when used as pilot controls. This model is directly actuated and operates independently of hydraulic pressure, enhancing its versatility in various system configurations. For models equipped with the D or L control, there is a detent mechanism in the manual override intended for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. Additionally, this valve incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The wet armature design of the DMDAXPV212 allows the working fluid to surround the armature which can be beneficial or detrimental depending on the duration the coil remains energized and the type of fluid used. The coil's compatibility with other Sun Series 1 solenoid products offers flexibility in maintenance and replacement processes. Furthermore, Sun Hydraulics' floating style construction minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), along with a fast typical response time of 50 ms and maximum leakage at high pressure being minimal, this valve is engineered for efficiency and reliability in controlling flow within hydraulic circuits.

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.
