The Sun Hydraulics DMDATPV814 (DMDATPV814) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control in hydraulic systems. Featuring a robust construction, the valve operates with no minimum hydraulic pressure required, ensuring reliable performance across a wide range of applications. The solenoid tube assembly is fatigue-rated for demanding 5000 psi (350 bar) service environments, enhancing its durability and lifespan. This valve model is particularly noted for its closed transition between Spools B and R, which provides faster and more consistent response times when used as pilot controls. The closed transition design limits capacity to achieve higher performance thresholds. For manual override applications, the DMDATPV814 includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Suitable for use with phosphate ester fluids thanks to its EPDM seals configuration, the valve should not be exposed to petroleum-based fluids which can damage the seals. Additionally, it features a wet armature design where the working fluid surrounds the armature; this requires consideration of fluid type as prolonged exposure to heat can lead to breakdown and varnish formation in susceptible fluids like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. The floating style construction incorporated into the design minimizes risks associated with internal parts binding due to installation or machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), this valve meets rigorous industrial requirements while maintaining precise control and response under varying 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.
