The Sun Hydraulics DMDADNV614 (DMDADNV614) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional mechanism. This model is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for high-performance applications. The valve's design includes closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDADNV614 operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic systems. It incorporates manual overrides with detent mechanisms that are designed for temporary actuation and can withstand approximately 7,000 cycles. Additionally, this model uses EPDM seals recommended for systems with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. This valve also benefits from a wet armature design where the working fluid surrounds the armature. This setup needs careful consideration as prolonged energization can lead to fluid degradation at high temperatures. The DMDADNV614 supports interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding due to installation variances or machining discrepancies. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min. The manual override requires an actuation force of about 5 lbs at 1000 psi per port. This model\u2019s cavity code is T11A and belongs to Sun\u2019s Series 1 line of valves, ensuring compatibility with standard setups in hydraulic systems requiring reliable directional control.

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.
