The Sun Hydraulics DMDALBV624N (DMDALBV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, featuring a direct-acting, balanced spool design. This valve is specifically engineered for use in applications where precise control of fluid handling is required. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it meets the rigorous demands of various hydraulic systems. The DMDALBV624N incorporates an innovative wet armature design where the working fluid surrounds the armature, which is beneficial for reducing wear but requires careful consideration regarding fluid type due to potential heat build-up during prolonged coil energization. It's important to note that cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model offers versatile manual override options with the D or L control providing a detent mechanism designed for temporary actuation. The mechanical life expectancy of these manual controls is around 7,000 cycles. Additionally, the valve features Sun Hydraulics' floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. For ease of maintenance and compatibility, the coils on this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This feature simplifies inventory management and enhances system design flexibility. The robust construction and thoughtful engineering make the DMDALBV624N an ideal choice for applications requiring reliable performance and high durability in challenging 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.
