The Sun Hydraulics DMDATNV614 (DMDATNV614) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve, designed for direct acting and balanced spool directional control. This model is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). It features a robust design with spools B and R that are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDATNV614 incorporates advanced design elements such as a wet armature setup where the working fluid surrounds the armature. This design aids in heat management but requires consideration regarding the type of fluid used due to potential breakdowns in certain fluids under prolonged exposure to heat. The valve's manual override mechanism is equipped with a detent feature intended for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Additionally, this model uses EPDM seals optimized for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based products. For ease of integration and maintenance, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction also features Sun's floating style to minimize internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This versatile component is an ideal choice for various hydraulic applications requiring reliable directional control and rapid response times under high-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.
