The Sun Hydraulics DMDAXPV814 (DMDAXPV814) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust construction with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve operates with no minimum hydraulic pressure required, making it versatile for various applications. The DMDAXPV814 incorporates 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. It also features a wet armature design; the working fluid surrounds the armature which can be an important consideration in systems where the coil may be energized for extended periods. For manual override operations, this model includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Coils on the DMDAXPV814 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Additionally, the valve utilizes EPDM seals specifically suited for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The floating style construction of the valve minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications including a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times of 50 ms, the Sun Hydraulics DMDAXPV814 offers reliable performance for advanced hydraulic system applications.

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.
