The Sun Hydraulics DMDALNV814 (DMDALNV814) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is particularly designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Engineered for precision and reliability, the DMDALNV814 boasts a rapid response time of approximately 50 ms and maintains maximum valve leakage at an efficient rate of 5 in\u00b3/min at 3000 psi. The valve's construction includes the innovative Sun floating style, which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This model integrates seamlessly with other Sun Series 1 solenoid products due to its interchangeable coils, which can be mounted in either direction on the tube. The wet armature design ensures that the working fluid surrounds the armature to manage heat during prolonged energization, although care must be taken with certain fluids that may degrade under heat. Additionally, this valve features manual overrides with detent mechanisms designed for temporary actuation, supporting about 7,000 cycles mechanically. It employs EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based fluids. With its robust build and versatile applications in systems requiring precise control and fast response times, the DMDALNV814 is an exemplary choice for advanced hydraulic control setups requiring meticulous flow management and 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.
