The Sun Hydraulics DMDATNV514 (DMDATNV514) is a solenoid-operated, 3-way, 2-position cartridge valve characterized by a direct-acting, balanced spool design. This valve is specifically engineered for high-performance applications with a fatigue rating suitable for 5000 psi (350 bar) service conditions. The DMDATNV514 features closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly in pilot control setups where flow capacity is less critical. This model operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. It also incorporates manual overrides with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of about 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature which can be crucial when considering the type of fluid used due to potential breakdowns from prolonged heat exposure. The DMDATNV514 is compatible with EPDM seals intended for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. Additional features include interchangeable coils with other Sun Series 1 solenoid products and a floating style construction that minimizes internal part binding due to installation or machining discrepancies. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 5 in\u00b3/min at 3000 psi. The manual override requires minimal force and the solenoid tube supports easy installation with versatile coil positioning. This model\u2019s robust design and adaptable features make it suitable for demanding applications requiring precise control and reliability.

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.
