The Sun Hydraulics DMDATBV514 (DMDATBV514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is versatile and robust, featuring a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve operates without minimum hydraulic pressure and incorporates a wet armature design where the working fluid surrounds the armature. This design is critical for understanding the thermal dynamics involved when the coil is energized over extended periods. The DMDATBV514 is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. It has manual override options with a detent mechanism designed primarily for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in repairs and replacements. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms. The valve ensures minimal leakage at high pressures (5 in\u00b3/min at 3000 psi) and supports up to 15,000 switching cycles per hour. Installation features include Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This valve's robust design and reliable performance make it ideal for applications requiring precise control over hydraulic flow and direction with considerations towards system fluid compatibility and thermal management during prolonged solenoid activation.

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.
