The Sun Hydraulics DMDATRV212 (DMDATRV212) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in various hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and capability to operate effectively under a maximum pressure of 5000 psi (350 bar). It features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve ensures precise control with spools B and R maintaining closed positions during transitions, enhancing performance by providing faster and more consistent response times. The DMDATRV212 operates without requiring a minimum hydraulic pressure, offering versatility in low-pressure applications. It includes manual override options with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. Configurations with EPDM seals are tailored for systems using phosphate ester fluids, while the wet armature design aids in heat management but requires consideration regarding fluid compatibility and potential breakdown when exposed to prolonged heat. This model is compatible with other Sun Series 1 solenoid products concerning coil interchangeability and can be mounted in either direction on the tube. It also incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations. With a flow capacity of up to 12 gpm (45 L/min) and swift response times typically around 50 ms, the DMDATRV212 is equipped to handle substantial switching frequencies up to 15,000 cycles per hour. This makes it an efficient choice for systems requiring frequent directional changes under varying 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.
