The Sun Hydraulics DMDATRV612 (DMDATRV612) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This versatile component is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve's response time is notably quick at approximately 50 ms, ensuring efficient operation in dynamic systems. Key attributes of the DMDATRV612 include its closed transition spools B and R, which enhance performance by ensuring faster and more consistent response times during the shift from one position to another. This makes it particularly suitable for applications requiring precise control with minimal flow loss. The valve operates without needing a minimum hydraulic pressure, thereby facilitating broader application use. For manual operation, the valve includes an override mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. It also features interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction for increased flexibility in system design. The construction incorporates Sun\u2019s floating style design to minimize internal part binding due to installation stresses or cavity/cartridge machining variations. Additionally, the wet armature design of this model means that the working fluid surrounds the armature; this is important to consider in applications where the coil may be energized for extended periods as heat buildup can affect certain types of hydraulic fluids. This model utilizes EPDM seals suitable for phosphate ester-based fluids but should not be used with petroleum-based fluids as these could damage the seals. Overall, the DMDATRV612 offers robust performance and reliability for specialized hydraulic applications requiring precise directional control and rapid response times.

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.
