The Sun Hydraulics DMDADRV212 (DMDADRV212) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar) service. The valve offers precise control with closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times ideal for applications where capacity is not the primary concern. Engineered to operate without minimum hydraulic pressure, the DMDADRV212 provides flexibility in installation and function. It incorporates various manual override options including D, L, and T controls, with a mechanical life expectancy of around 7,000 cycles. The model is particularly suited for systems using phosphate ester fluids as it employs EPDM seals which are resistant to this type of fluid but can be damaged by exposure to petroleum-based substances. Furthermore, the DMDADRV212 uses a wet armature design allowing the working fluid to surround the armature which could potentially affect fluid integrity under prolonged energization. It supports a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures of 5000 psi (350 bar). The valve's quick response time is typically around 50 ms, and it features interchangeable coils compatible with other Sun Series 1 solenoid products. This valve also benefits from Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With these capabilities and specifications, the DMDADRV212 stands out as a reliable component for advanced hydraulic systems requiring precise directional control and durable performance under high-pressure conditions.

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.
