The Sun Hydraulics DMDALRV914 (DMDALRV914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure, ensuring reliable function under various conditions. The DMDALRV914 incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances the valve's durability and operational reliability. The solenoid tube assembly is specifically designed to be interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system configurations. Additionally, this model is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The valve also utilizes a wet armature design where the working fluid surrounds the armature; this requires consideration of fluid type as some may degrade at higher temperatures. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), the DMDALRV914 is capable of handling substantial hydraulic loads. It offers quick response times typical at 50 ms and maintains control accuracy with a maximum leakage specification of 5 in\u00b3/min at 3000 psi. The manual override feature requires minimal force, enhancing ease of use during temporary actuation. Overall, the Sun Hydraulics DMDALRV914 valve is an efficient solution for directing hydraulic flow in sophisticated systems requiring precise control and high reliability.

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.
