The Sun Hydraulics DMDAXBV624 (DMDAXBV624) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). Its quick response time of approximately 50 ms and a switching frequency of up to 15,000 cycles per hour make it suitable for applications requiring frequent and rapid switching. The DMDAXBV624 features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve operates without a minimum hydraulic pressure requirement, adding to its versatility across various hydraulic systems. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design aids in cooling but requires consideration of fluid compatibility due to potential breakdowns at high temperatures. For ease of maintenance and adaptability, the solenoid coils on this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. The construction incorporates Sun\u2019s floating style design which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This model also includes manual override capabilities with a detent mechanism designed for temporary actuation only. The manual control assembly has an expected mechanical life of around 7,000 cycles. In terms of installation, the valve features a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30 \u2013 35 lbf ft (41 \u2013 47 Nm), ensuring secure fitting without over-tightening.

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.
