The Sun Hydraulics DMDADBV (DMDADBV) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDADBV is well-suited for demanding hydraulic systems. The valve features closed transitions between positions for Spools B and R, ensuring faster and more consistent response times which are crucial in pilot control applications where capacity is less critical. This design choice contributes to the valve's ability to handle high-performance limits effectively. The manual override options available with the D or L control have a mechanical life expectancy of approximately 7,000 cycles, indicating durability in temporary actuation scenarios. Equipped with EPDM seals, the DMDADBV cartridge is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. Additionally, its wet armature design allows the working fluid to surround the armature which can be a consideration when coils are energized over extended periods due to potential heat buildup affecting fluid integrity. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement scenarios. Also incorporating Sun's floating style construction minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With these advanced features combined with a rapid typical response time of about 50 ms and switching frequency up to 15,000 cycles/hr, the Sun Hydraulics DMDADBV valve stands out as an effective solution for sophisticated hydraulic controls across various applications.

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.
