The Sun Hydraulics DMDAMBV624 (DMDAMBV624) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is particularly noted for its robust construction with the solenoid tube assembly being fatigue rated for up to 5000 psi (350 bar). It offers precise control by maintaining closed spools B and R during transitions, which enhances performance at the cost of lower capacity. However, this feature makes it ideal for pilot control applications where consistent response times are critical rather than flow capacity. The DMDAMBV624 operates without requiring a minimum hydraulic pressure, adding to its versatility in various hydraulic systems. It includes options for manual override controls (D, L, and T types), each designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the valve can be equipped with EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. This model also employs a wet armature design allowing the working fluid to surround the armature. While this aids in heat absorption when the coil is energized continuously, it might accelerate fluid breakdown in certain conditions such as with water-glycol mixtures. The interchangeable coils compatible with other Sun Series 1 solenoid products provide flexibility in maintenance and replacement. Further enhancing its reliability and ease of installation, the DMDAMBV624 features Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications like a flow capacity of 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), along with rapid response times averaging 50 ms and low leakage rates at high pressures, this valve is engineered to meet demanding hydraulic control requirements efficiently.

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.
