The Sun Hydraulics DMDATNV814N (DMDATNV814N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly without minimum hydraulic pressure, making it highly effective for various applications requiring reliable directional control of fluid flow. The valve features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), ensuring durability and a long service life under high-pressure conditions. The DMDATNV814N model incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially useful in pilot control applications where capacity is less critical. Additionally, the valve's wet armature design allows the working fluid to surround the armature which could be crucial in applications where the coil may be energized for extended periods. With a flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, this valve ensures efficient operation with minimal delay. It supports a maximum operating pressure of 5000 psi (350 bar) and exhibits maximum leakage at 110 SUS (24 cSt) of only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The manual override feature requires minimal force and includes detent mechanisms designed for temporary actuation with an estimated mechanical life expectancy of about 7,000 cycles. This model also features interchangeable coils with other Sun Series 1 solenoid products for versatile use and easy maintenance. The floating style construction minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations, enhancing reliability in diverse operational contexts. Ideal for systems using phosphate ester fluids, this valve should avoid exposure to petroleum-based fluids which can damage its EPDM seals.

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.
